There are several high-standard hotels throughout the country, most of which are run by well-known international chains. Amman and Aqaba, in particular, have a good choice of hotels. Hotels are fully booked during business periods so reservations are advised. Rates can be negotiated in Winter. All rates are subject to 20 per cent tax and service. There are serviced apartments available. Grading: Hotels are graded from 5- to 1-star. 5- and 4-star hotels have discos and nightclubs with live music. Prices are fixed by the Ministry of Tourism, which can also deal with complaints. For further information, contact the Ministry of Tourism or the Jordan Tourism Board (see Top Things To Do).
