Room types and real room numbers
The type sets the price. The numbers are the rooms a guest is actually given.
A room type — Deluxe, Executive, Suite — is what is sold and what carries a price. The rooms under it are the physical rooms, with the numbers on the doors.

Do this
- Code and name of the type — STD, Standard.
- Sleeps — the normal occupancy.
- Room numbers — the real numbers, typed as a list or a range: 101-108, 201, 204. A number is never reused in a hotel.
- Add a room type for the next one.
- Type them as guests will read them: 101, 102, 201. Not "Room 1".
- For the OTAs, or internal only? The form asks. A type for the OTAs is registered with the channel manager the moment it is saved and goes out on every push from then on; an internal type is sold at the desk, the CRS and the booking engine and never leaves the building. A parking category for rooms you do not sell online is the internal kind. Change your mind on Edit category — taking a type off the channels retires its mapping, so the pushes stop carrying it.
- Every type needs at least one room, or nothing under it can be sold.
- The order of the types is the upgrade ladder. An upgrade moves a guest up it, so put them in the order a general manager would.
- Adding a room later is ordinary. Removing one that has history is not — take it out of order instead, permanently if the room no longer exists.
Availability is counted from these rooms. A hotel that types thirty rooms and owns forty will sell out ten rooms early, every night, and nobody will notice for a month.
The day-use switch
A category can also be marked as one a day guest may be put in — the day use tag. It reserves nothing and takes nothing off that category's nightly sale; it is read only when the desk looks for a room to give a day guest at the door. See Day use: a room sold for the day, not the night.
