Reservation Types Summary
"Freeform" reservations offer the most flexibility for time and pricing but cannot be used for online reservations. When used for a top-level facility, you can still display the facility online, but cannot allow reservations for the top-level facility. Sub-level facilities will have a separate reservation type and can be reserved online if the facility uses a reservation type that allows it.
"Predefined Time Slots" are used to set specific availability windows for facility reservations.
"Resource" Will only be used when the specific facility being reserved doesn't matter and you only care about the time of the reservation.
"Campground" is the top-level facility for creating campsites.
