The week before your party, the birthday party coordinator will contact you to confirm the number of kids so that your party will be staffed accordingly. If you are expecting more guests than you registered when booking your party, you can let the birthday party coordinator know when they reach out. If you are expecting more or fewer guests than you confirmed with the birthday party coordinator the week of, please let us know. Our office number is 341-1175. If you have confirmed 16+ in attendance for your party, we will staff two coaches. If fewer than 16 show for the party, you are still required to pay for 16 students due to the staffing of two coaches.
