Badminton Outing RSVP Website: Racket Counts, a Court Cap, and a Shuttle Line
A badminton outing RSVP has to lock a racket and a court before the rotation is written, because a maybe does not hold a racket.

A badminton outing breaks when three courts were booked for twelve players and eighteen people walk in, or when the shuttle tube was bought for a count that included four maybes who never came. Rackets, the court each four will use, and the shuttle you will actually hit are set before anyone tapes a line. The host does not claim a fourth court because a neighbor decided to play after the gym hold closed. A maybe does not hold a racket.
You can create a badminton outing RSVP that fills the courts you will actually book, records a racket for each person who will play, and stops when those courts are full.
Count the players the courts can hold
Walk the gym before you send the link. Write down how many courts are inside the block, whether the lines are already down, and how long you have the floor before the next group. If you have three courts for ninety minutes and doubles puts four players on a court, twelve is your cap. A person hitting against the wall is not a thirteenth player. The court is the game you reserved.
A racket is one player. Ask whether a friend who will not play can sit on the bench, and whether that person still counts toward the number the gym put on the permit. Pick one rule and write it on the page. Watchers stay off the court. They do not rotate in "for one game" and leave you with a fifth body on the lines.
Ask the last time you can change the court count without losing the hold. If the desk wants a final number on Thursday for a Saturday block, that Thursday is your lock. Write the finish too: one block, the courts you named, done when the clock starts the next booking. Staying late because a game is close is not a plan.
Set a capacity limit on people who will play, not on everyone who was invited to sit. When the last court spot is taken, the form should say the outing is full. If the rotations are already written, a late friend is not on this floor.
The shuttle line is a tube, not a mix
Name the shuttle you will open and stop there. A clear line is one tube of nylon indoor shuttles in the speed the gym plays, opened at the start, with house rackets for anyone who does not own one. Each person confirms they will play with that shuttle. Feather shuttles, an outdoor nylon that dies on this floor, and a homemade bird are a different session. They change the flight for all four people on the court.
Put racket choice on the form in the choices you can honor: own racket, or a house racket. If the house set is eight rackets, do not promise a ninth. People who want to drill alone should not take a court that was built for doubles. You need a yes to this shuttle and this court before you write a rotation.
Households, and a time to be on the floor
Outings go wrong when one adult yes hides two more players. One person who brings two family members is three rackets and three spots, not one. Use a household RSVP so each player has a name before you count them against the court cap. A family member plays only if a spot is still open. They do not share a racket for the block.
Courts sit dark when people arrive in a clump at the middle of the block. Collect an arrival window that matches the gym door, not a vague afternoon. The window might be 9:40 to 9:50 for a 10:00 start, so rackets can be checked before the first serve. Write what happens if someone is later than that: the spot goes to a standby who is already in the gym, or the court plays a three and the late person does not enter the rotation. Court shoes are part of the same yes. Say that on the page. Street shoes mark the floor, and the gym will charge you for it.
The moment the rotation is locked
The meeting point is the gym door you named, not "the rec center" with three buildings. Put your phone on the page. A message that says "save me a court" is not a racket. You match names to the rotation.
Tie the deadline to the hold, the day the desk will not add a court. After that, a late yes is a call about a cancellation, not a promise of another racket. If you want names ready when someone drops, keep them as standbys and tell them they do not have a court until you write back. A maybe does not hold a racket.
Export the list the morning you lock: attending or not, own racket or house racket, household names, arrival window, and phone. A badminton RSVP is finished when every court has four named players, the shuttle is the tube you already bought, and a late car knows whether they are playing or going home.
