Cave Tour Outing RSVP Website: Helmet Counts, a Group Cap, and a Stair Line
A cave tour outing RSVP has to lock a helmet and a guide spot before the group leaves the visitor center, because a maybe does not hold a helmet.

A cave tour outing breaks when the guide issued twelve helmets and eighteen people are at the gate, or when someone who said maybe arrives after the group has gone through the door and expects a lamp that was already checked out. Helmets, the size of the group one guide will take, and the stair line you agreed to are set before the first lock opens. The cave does not add a guide because a friend decided to come after the helmet list closed. A maybe does not hold a helmet.
You can create a cave tour outing RSVP that fills the helmets the cave will issue, records who can do the stairs and the dark, and stops when that tour window is full.
Ask what the cave will actually take
Call the cave before you send the link. Write down the tour you are buying, how many people that guide will take, whether the route is the paved path or the wet wild section, how long you are underground, and whether helmets and lamps are included. Those numbers are your cap. Do not guess from the length of the parking lot.
A helmet is one person through the gate, not one car and not one family. Ask whether a toddler in arms still needs a helmet, the age or height minimum for this route, and whether a shorter paved tour uses a different time and a different cap. Pick one tour and write it on the page. If you are doing both a paved slot and a wild slot, those are two lists with two caps. Do not mix them and sort people out at the gate.
Ask the price, whether a waiver is signed at the visitor center, and the last time you can cut the count without paying for helmets the cave already pulled for your clock time. If they charge for a no-show after that time, print that rule on the page. A paved-path ticket is not a pass for the wild route.
Set a capacity limit on people who will go underground, not on everyone who was invited. When the last helmet in your window is taken, the form should say the outing is full. A friend who might come still needs a helmet and a place in a group the guide is staffed for. If the cave has already counted your group, they are not in this window.
The stair line is a yes or a no, not a vibe
Ask the cave what this route does: wet stairs, a low duck-under, a stream crossing, mud, and a minute with the lamps off. Put that list on the page in plain words. Each person confirms they can do that route, or they pick the paved tour if one exists and still has helmets.
If the cave will not run a step-free path, say that. People who cannot do stairs, a crouch, or a full minute of dark should not take a helmet. You do not need a diagnosis. You need a yes or a no before the guide staffs your window. A preference the cave cannot meet should not be on the form.
Wet rock, no stroller, and a group that stays with the guide
Most cave paths are stepped, slick, and too narrow for a stroller. Ask about access needs the cave can actually meet: the paved route if one exists, or a seat at the visitor center. If every route has stairs and no exit until the end, say that.
Ask the maximum the guide will take past the gate. If they move people in tens, put that cap on the form and do not let one household claim fourteen spots. Read the weather rule the cave gave you and print it. If rain floods the entrance or ice closes the trail to the mouth, the tour does not go, and a maybe does not hold a helmet for a makeup slot you have not bought. Collect an arrival window that matches the visitor center, not the cave mouth. The window might be 1:10 to 1:20 at the ticket desk. Write the clock time and what happens if someone is later than that: the guide leaves, and the cave does not send them in alone.
The moment the helmet list is locked
The meeting point is the visitor center the cave assigned you, with the desk name if there is more than one. Put the host's phone on the page for the person holding the group reservation. A screenshot of the invite is not a helmet. The person at the desk matches names to the count you sent.
If you allow a guest, that person needs their own helmet line, their own stair-line answer, and their own arrival window. Track them as a separate yes. One form that hides an extra walker will blow the guide's cap. Say that on the page. Children count if the cave said they need a helmet. Write the age and height rule next to the question.
Tie your RSVP deadline to the cave's final count, the day they lock your tour. After that, a late yes is a call about a cancellation, not a promise of another helmet. If you want names ready when someone drops, keep them as standbys and tell them they do not have a helmet until you write back. A maybe does not hold a helmet.
Export the list the morning you lock: attending or not, paved or wild, party size, arrival window, access note the cave agreed to, and phone. A cave tour RSVP is finished when every helmet has a named person, the stair line matches a route the cave will open, and a late car knows whether they are going in or going home.
