The maximum number of people that a room can physically accommodate.
The capacity of a room is always equal to or higher than the occupancy. For example, the "Honeymoon Suite" might have a maximum capacity of six people, but you price a bundle for two guests (while capacity is six, you set occupancy to two).
To define set the value of a package's capacity in a Transaction message, use the
<Capacity> child element, as described in Transaction Messages.
