Hotel Classification: The following designations are generally understood throughout Europe and, to an extent, the world, but it is sometimes difficult to know whether a hotel is being described by a reliable source or at the whim of a promoter. There is neither an official nor generally -accepted rating system for U. S. hotels.

Deluxe: In travel usage, presumably 'of the highest standard'. A much misused and, in many respects, meaningless term except where employed as part of an official rating system.

First Class: A medium-range hotel; at least some rooms have private bath; most of the usual public rooms and services are provided.

Tourist (Economy or Second Class): Budget operations; few or no private baths; services may be very limited. The Official Hotel & Resort Guide further subdivides these three categories into three groups; superior, average and moderate. Thus, a superior, deluxe hotel rates with the best in the world and an average, first class hotel is about in mid-range. OHRG says that Westerners should use hotels below its superior tourist rating with caution. In addition, many governments rate their hotels according to the international five-star system under which a five star hotel is the best. Some countries are meticulous and generally current in their ratings; many are not. In general, three star and better hotels (and a few two-star properties are believed suitable for Western travelers).
