Hotels, motels, and guesthauses may be single-room or multiroom, long- or short-term dwelling (or residence) units;
they may be stacked sideways and/or vertically.

Hotel and motel accommodations are usually single guest rooms
with a toilet and bath adjacent to a corridor, and flanked on both
sides by other guest rooms. The building may be single-story, lowrise,
or high-rise. Multipurpose subsidiary facilities range from
stores and offices to ballrooms, dining rooms, kitchens, lounges,
auditoriums, and meeting halls. Luxury motels may be built with
similar facilities. Occasional variations are seen, such as kitchenettes,
multiroom suites, and outside doors to patios and balconies.
Hotel classes range from the deluxe hotel to the economy
hotel/motel
A hotel can be divided into three main areas:
1. Guest rooms
2. Public areas
- Lobby, atrium, and lounges
- Ballrooms
- Meeting rooms
- Restaurants and dining rooms
- Stores
- Swimming pools
- Health clubs
3. Back-of-the-house (BOTH) areas
- Kitchens
- Storage areas
- Laundry
- Offices
- Service areas and equipment rooms
The two main areas of use are the guest rooms and the public
areas. Maximum comfort in these areas is critical to the success of
any hotel. Normally the both spaces are less critical than the
remainder of the hotel with the exception of a few spaces where a
controlled environment is required or recommended.
Guest Rooms
Air conditioning in hotel rooms should be quiet, easily adjustable,
and draft free. It must also provide ample outside air. Because
the hotel business is so competitive and space is at a premium, systems
that require little space and have low total owning and operating
costs should be selected.
