Why a bus needs a real RSVP deadline
At a house party, one more person is one more chair. On a bus, the seat count is locked the moment the vehicle is reserved.
If three people say yes after you've booked an 18-passenger party bus for 18, they don't ride. On a busy weekend there may be nothing bigger left.
So give your group a real date, and set it before you have to pick a vehicle, not after. "Tell me by the 10th or I can't hold you a seat" is kinder than it sounds.
That's also why the seat line counts pending guests alongside confirmed ones. Until somebody says no, plan as though they're coming. If your list is still mostly maybes, get a rough number from the group size calculator and firm it up here.

Chase the money with the yes
A yes that hasn't paid is a softer yes. Organizers who collect up front see far fewer late dropouts, because people protect a plan they've already put money into. That's why the paid checkbox sits right next to the status button.
Work out each share with the split cost calculator once you have a quote, then let the copied list do the asking. A message showing ten names marked paid and two that aren't tends to solve itself overnight.
One warning on the math. If your share assumes 14 riders and two drop, everyone else pays more. Decide early whether a late cancellation still owes, and say so in the chat while people are still agreeable. Deposits and cancellation terms for the vehicle itself are on your written quote.
One person owns the list
Groups fall apart when two people keep two lists. Pick one organizer who owns the names and route every change through them. Because this tool saves to one browser on one device, it fits that setup naturally, and everyone else works off the copied summary.
While you're gathering names, settle the pickup address too. One pickup and one final drop-off use your hours far better than a loop through four neighborhoods. If people are scattered, pick a central house or a lot where cars can sit overnight, and sanity-check it in the route planner.
For prom groups and any trip with riders under 18, keep a parent contact for every student somewhere of your own, like your phone contacts. Don't put it in here. One adult should own both the list and the booking.

When to start asking
How much runway you have depends on what you're planning. Bachelor and bachelorette groups here start about six weeks out, roughly two weeks earlier than everyone else, because flights and a rental house come first.
If that's you, open the list the day the flights are booked. Your names firm up early, and that's a real advantage.
Birthdays are the opposite. Most Valley birthday groups call us about three weeks ahead, one of the shortest windows we see, and small groups run on the same clock.
Three weeks isn't long. Send the invite, set the deadline a week later, and ask for a quote the moment you have a number.
Milestone birthday parties with 20-plus guests should start sooner than that. A countdown helps people take the deadline seriously, so set one in the event countdown timer.
Who can see your list
Nobody but you. It sits in your browser's local storage, never gets sent to us or anyone else, and that cuts both ways: it won't show up on your other devices, and it disappears if you clear your browsing data. Use "Copy list" to keep a backup in your notes.
The tool only asks for names, and that's on purpose. Don't type phone numbers, emails or addresses into the name field. First names run an RSVP perfectly well. On a shared or public computer, hit "Clear all" when you're finished.
Once the list is closed, the only thing we need from it is the rider count. Put that on your quote request with the date, the pickup city and the hours you want, and keep the names to yourself.
