Some hotels are built specifically to create a captive trade, example at casinos and holiday resorts. Though of course hotels have always been built in popular desinations, the defining characteristic of a resort hotel is that it exists purely to serve another attraction, the two having the same owners.
In Las Vegas there is a tradition of one-upmanship with luxurious and extravagant hotels in a concentrated area known as the Las Vegas Strip. This trend now has extended to other resorts worldwide, but the concentration in Las Vegas is still the world's highest: nineteen of the world's twenty-five largest hotels by room count are on the Strip, with a total of over 67,000 rooms.
In Europe Center Parcs might be considered a chain of resort hotels, since the sites are largely man-made (though set in natural surroundings such as country parks) with captive trade, whereas holiday camps such as Butlins and Pontin's are probably not considered as resort hotels, since they are set at traditional holiday destinations which existed before the camps.
