From the classic midway and free circus acts under the pink-and-white big top to the thrilling rides in The Adventuredome, Circus Circus Hotel, Casino & Theme Park -- with its inexpensive rooms -- has been a family favorite since it opened in 1968. As you might expect from something called the Manor Motor Lodge, the rooms are the cheapest, but also the smallest, least modern and least convenient. Housed in several three-story motel-style buildings that are detached from the property, you'll have to walk a good ways (including across a four-lane street) to get into Circus Circus Hotel, Casino & Theme Park's lobby and casino.
