Setting up Scheduling for Golf Tee Times

Hi! I'm a designer setting up a website for a client. This client offers mini golf, and would like me to set up booking for tee times through their website. Unfortunately, even though I've used SS Scheduling before, I cannot figure it out. It would need to be as follows:

Tee times starting every 10 minutes. Ticket pricing is Adult $12, Child $10, Kids 5 and under are free.

I've tried setting this up as an appointment, with Adult, Child, and Kid as add-ons. The issue with this is that you cannot add multiple of each add-on to an appointment.

If anyone can figure out a way to set this up, that'd be great! Thanks in advance!
