WooCommerce Bookings

Currently there is no way to prevent a single user from booking multiple bookings on a single day. In our case, we want to limit the number of total persons available for the day to 100. Each user should only be allowed 1 booking per day with up to 5 persons. We don’t want an individual to be able to make 20 bookings with 5 persons each, because then that 1 person would have booked up the entire 100 slots available for the day. Currently there is no way to prevent somebody from doing that. They can schedule a booking for 5 persons, then if they go back to the product they can schedule another booking for the same day for 5 more persons, and so on. WooCommerce Bookings lets them do this as many times as they want, with no setting to prevent it from happening.
