Multiple people booking at the same time

I meant I need to be able to have multiple people at the same time. I have the service limit at 0 and I also tried it with 10. Still doesnt allow multiple people to book.

Hi @Rex,
You are welcome to the WPMU Dev community and thank you for your question.
You can integrate Appointments+ plugin with MarketPress eCommerce plugin as explained in the following reply to book multiple appointments at a time.
