The number of persons is the maximum number of persons that can book your product per day according to the availability you set.

For example, if you set the maximum number of persons to 500 and your availability is 3 different time slots, you will be able to have 500 bookings per time slot (at 08:00, 10:00 & 12:00) so 1500 bookings in total. 

In the case where you have opening/operating hours, you then limit the number of people bookable per day (500 per day in this case).

In order to not miss out bookings, we strongly recommend you to set the number of persons as high as you can.
