A booking in MakePlans ends up in the calendar of a resource. By default the capacity on a resource is 1 so there is only 1 booking for 1 person at a specific timeslot. But this can be adjusted to allow multiple bookings or multiple people pr booking within the same specific timeslot.
To allow multiple bookings pr timeslot set capacity to be more than 1. Let's say you want to have 5 simulations bookings pr timeslot then set capacity to 5.
Nr of people pr booking is controlled by the service. So if you want to have max 4 people pr booking set 'Max nr of people pr reservation' to 4 on the service.
For a resource with capacity 5, the resource will be fully booked when either there are 5 bookings or bookings with multiple people that adds up to 5 (for example one booking for 2 people and one booking for 3 people).
