General Settings  

Some fields in General Settings refer to the GDS (Global Distribution System) and other networks inclusive in the Global Booking Networks. If you have not elected to use the GDS, you can skip over some fields. If you are not sure, or have questions contact BookingCenter.
(GDS) "Adult rates pertain to all guests over X years old". If you give a reduced rate for Children, this field determines the age of Adults.
When guests make bookings, the system will ask how many occupants. The number of occupants controls the maximum number of guests that can be booked into a specific room type and it may determine price if you use 'Per-person' pricing.
