Aggregate only
We run grouped counts and medians, nothing else. Names, phone numbers, email addresses, street addresses, free-text messages and payment fields are never read, exported or published.

Summary
Where every number comes from
If a statistic appears anywhere on this site, it came from one place. There is no second source, no national dataset and nothing borrowed from an industry report.
That place is 2,678 Phoenix-area trip inquiries received from June 2023 to September 2026 through Phoenix Party Bus and affiliated Phoenix-market booking channels. We publish grouped counts and medians only, never a finding with fewer than 40 records behind it, and we call the results inquiries and historical quotes rather than bookings and prices.
The findings themselves live on the Phoenix transportation data page. This page is about how they were made.
Publication rules
Six rules every finding follows
Minimum cohort of 40
A finding goes up only when at least 40 records sit behind it. Anything smaller gets dropped rather than published with a warning label on it.
Rounding
Percentages are rounded to whole numbers, and so are quote medians, which is why they read as about $1,250 rather than to the dollar. Shares within a finding can total 99 or 101.
Per-finding sample size
Fields on an inquiry are optional, so each finding reports its own n instead of borrowing the headline 2,678.
Inquiries, never bookings
Every sentence describes what people asked for. We do not record which requests became trips, so we make no claims about bookings, revenue or market share.
Historical quotes, never prices
Quote medians span more than three years and a lot of vehicle types. They are history, not an offer and not a rate card.
What is measured
What we measure, and how often
Plenty of people send us a date and a phone number and nothing else, which is completely fine for booking a bus and awkward for counting things. So coverage differs by field.
The counts below are the largest sample available for each one.
| Field | Records | Used for |
|---|---|---|
| Event dateDay of week and month of the requested trip. Drives the weekday and seasonality findings. | 2,336 | Day of week and month of the requested trip. Drives the weekday and seasonality findings. |
| Inquiry date and event dateDays between the inquiry and the event. Drives the planning-window findings. | 2,580 | Days between the inquiry and the event. Drives the planning-window findings. |
| Passenger countRequested group size. Drives the group-size bands and medians. | 1,809 | Requested group size. Drives the group-size bands and medians. |
| Stated occasionEvent type chosen or stated by the customer, such as prom, wedding, or birthday. | 1,057 | Event type chosen or stated by the customer, such as prom, wedding, or birthday. |
| Quoted vehicle typeCategory of vehicle quoted: party bus, Sprinter limo, or stretch limousine. | 717 | Category of vehicle quoted: party bus, Sprinter limo, or stretch limousine. |

Definitions
What each measure means
Four words do most of the work on the data page. Here is exactly what each one counts, so nothing you quote gets stretched by accident.
- Planning window. Days between the date an inquiry arrived and the requested event date. The headline figure is the median, 31 days.
- Group size. The passenger count the customer entered, banded 1 to 10, 11 to 15, 16 to 20, 21 to 30 and larger. It is a requested number, and the final headcount often differs.
- Vehicle mix. The category of vehicle quoted back, which reflects both what the group asked for and what actually fit them.
- Historical quote. The total quoted for the whole trip. Not an hourly rate, and not what anyone ended up paying.
Confidence grades
What the A, B and C mean
Every finding carries a grade, and it tells you one thing: how much data is holding it up. Of the 78 published findings, 12 are grade A, 26 are grade B and 40 are grade C.
Grade A
1,000 or more records
Market-wide patterns such as weekday, month, group size, and lead time. Stable.
Grade B
200 to 999 records
Large segments such as bachelorette trips, birthdays, trip length, and overall quotes. Reliable.
Grade C
40 to 199 records
Single-event breakdowns such as prom, weddings, and concerts. Directional.
A grade C finding is still worth using. When 83% of Phoenix prom inquiries are for a Saturday, the exact figure might be a couple of points off, but the point made in the prom party bus guide — that every family wants the same handful of nights — does not move.
If a number on this site isn’t traceable here, tell us.Older versions of these pages quoted catalog counts and national, multi-market figures. Those are gone. Everything now traces back to the Phoenix dataset, and if you find one that doesn’t, send it through the contact pageand we’ll fix it.
Phoenix Party Bus data
The rules in practice
Four findings from one measure, each with its own sample size and grade.
66 days
Big groups plan roughly three times earlier than small ones. If you are moving 40+ people, two months of runway is typical.
31 days
A month ahead is normal. Earlier gets you first pick of sizes; later still works, with fewer options.
26%
Last-minute trips happen constantly. Call instead of emailing when you are inside two weeks so availability can be checked live.
38%
Small groups decide late and usually still find a limo or Sprinter. Big groups do not have that luxury.

How the site uses the data
How a finding reaches a page
All the findings sit in one source file, each with an ID, a short statistic, a sentence that is safe to quote, a plain takeaway, a sample size and a grade.
Pages pull from that file instead of retyping numbers. So when a wedding transportation page and a coach bus page both mention the 77-day wedding planning window, they are reading the same record. Fix it once and it is fixed everywhere.
Our planning tools carry the same labels. Whatever the party bus cost estimator shows you is a budgeting aid built on history. Only a quote for your actual date is a price.
Opinions stay on their own side of the fence. The rider polls are self-selected votes from site visitors, and they never get mixed into these findings.
Where the rest of our advice comes from
Streets, airports, venues and weather are not in the inquiry data, so we point you at the agency that owns the answer. Closures, airport rules and heat warnings change faster than any web page does, and a stale number is worse than a link. The registry below lists those sources.

Methodology questions
Straight answers on minimum hours, deposits, what is included, and what to bring.
A request for availability or a quote for a trip in the Phoenix metro, received through Phoenix Party Bus or an affiliated Phoenix-market booking channel between June 2023 and September 2026. That covers pickups in Phoenix, Scottsdale, Tempe, Mesa, Chandler, Gilbert, Glendale, Peoria and the surrounding Valley cities. Anything for another market is left out.
Two reasons. Below roughly 40 records one unusual week can swing a percentage by several points, so the finding would not hold still. A floor also protects privacy, because a very small group can sometimes be traced back to a real event. Segments that do not reach 40 are dropped entirely.
This is the people who contacted us or an affiliated Phoenix channel, not every group in the Valley. It leans toward celebration travel, because that is what party buses and limousines get used for, and away from daily commuter or school transportation. Optional fields also mean quote and trip-length findings rest on fewer records than date findings.
Because one 56-passenger, twelve-hour charter would drag an average upward and make the typical trip look bigger than it is. The median is the middle request, which is closer to what a planner actually wants to know: what is normal for a group like mine.
No. They are raw medians of recorded quotes across the whole period and across vehicle types within each segment. That is a big part of why we call them historical and tell you not to read them as today's price. They are better for comparing segments, like Saturday against Friday, than for predicting your quote.
A record missing the field a finding depends on drops out of that finding, which is why sample sizes vary. And since only non-identifying fields are read, repeat requests from the same group cannot be matched and merged, so someone who inquired twice may be counted twice. At this sample size with rounded percentages, the effect is small.
No. Those contain customer information and are not shared in any form. What we publish, and what you are welcome to cite, is the aggregate layer: every finding with its sample size and grade, all on the Phoenix transportation data page.
Use the contact page or email info@phoenixpartybus.net with the finding ID, like PHX-009, and what looks wrong. If we confirm a correction, the finding changes on the data page and everywhere else on the site at once, because every page reads the same source file.
