Ski Day RSVP Website: Lift Tickets, Rentals, and Lesson Groups
A ski day RSVP has to separate lift tickets, rental sizes, and lesson spots before you pay, because a maybe does not hold a boot.

A ski day breaks when you buy lift tickets for maybes, when rental boots are the wrong size because nobody asked, or when the lesson meets at a different time than the friends who are only skiing. The mountain sells tickets, a rental window, and a class size. A maybe does not hold a boot.
You can create a ski day RSVP that separates ticket holders, rental needs, and lesson groups, and stops when the booking is full.
Ask what you are actually buying
Call the mountain, the rental shop, and the bus company if you have one, before you send the link. Write down whether tickets are date-specific, whether a child ticket has an age or height rule, and the last time a name or a size can change. Ask how many people one lesson group holds and what time that group meets, which is often earlier than the friends who already ski. Ask whether a helmet is included with the rental or is a separate line. Those answers are your caps. Do not guess from a trail map.
Set a capacity limit on the thing that runs out first. That might be bus seats, lesson spots, or the number of tickets you are willing to buy before the refund window closes. Say which limit the form is enforcing. When the last lesson spot is taken, a later yes can still be a ticket-only skier if you have tickets left, but only if the form lets those be different lines. One blob of yeses will not tell the shop who needs a boot.
If the mountain will add a ticket only when you call before a clock time, print that time. A name added after you have paid is a person you are buying for at the window rate, if a window ticket even exists that morning. Say that so a late yes knows it is not the group price. A child ticket and an adult ticket are different lines if the mountain prices them that way. Ask age on the form only because the ticket rule needs it, and say why.
Tickets, rentals, and lesson groups
Ask each person to pick one plan:
Ticket and rental counts against the ticket cap and needs the sizes the shop asked for
Ticket only, own equipment counts against the ticket cap and does not need a boot
Lesson plus ticket counts against both the ticket cap and the lesson cap, and meets at the lesson time
Not attending is a no, not a maybe that holds a ticket until the bus doors close
Ask for the rental details in the shop's words: boot size or shoe size, height, weight, skier or snowboarder, and whether they want a helmet. A wrong boot is how a morning disappears in the rental line. If the shop wants pounds and inches, ask for pounds and inches, not a guess labeled "average." Ask ability in the words the lesson desk uses, often a first-timer, a cautious skier who can stop, or someone who does not need a lesson at all. Do not put a first-timer on a ticket-only plan because the lesson looked full and you hoped they would keep up with friends.
If you are riding a bus or carpooling, ask who needs a seat and who is driving, and match that number to the bus you chartered. A skier who is driving themselves still needs a ticket answer. Gear in the aisle is the bus company's rule. If they said skis go underneath, print it. Count snowboard bags the same way you count seats: a bag that does not fit is a person you cannot add the night before.
Weather, the lodge, and when the list locks
Put the weather plan on the page before anyone pays their share. Say who decides to move or cancel, what time they decide, and whether a ticket is refundable, credited, or already spent. A guest who can only come on the original date needs a way to say that so you are not holding a lesson spot for a Sunday they cannot make. Wind that closes a lift is the mountain's call. Your job is to have said what happens to the money and the roster when that call comes.
Ask who is eating at the lodge and whether anyone needs a slower pace, a seat on the bus, or help with a long walk from the lot. Check what the mountain can actually offer before you promise it. Write the bus time, the rental time, and the lesson time as three clock times. They are not the same minute. A lesson that starts at 9:30 does not survive a bus that arrives at 9:40.
Tie your RSVP deadline to the ticket and rental cutoff, whichever is earlier. After that, a late yes is a call about a cancellation, not a promise. Keep subs off the manifest until you write back. Export the list the day you lock: ticket plan, lesson or not, rental sizes the shop asked for, bus seat or driving, phone. A ski day RSVP is finished when every ticket has a name, every rental has a size, and the lesson desk is not sorting your group at the meeting sign.
