The High Roller is a 550-foot observation wheel at the eastern end of The LINQ Promenade, midway along the Las Vegas Strip. Twenty-eight spherical glass cabins, each air-conditioned and holding up to 40 passengers, complete a single rotation in about 30 minutes. An audio commentary plays during the revolution, covering the history of the resort corridor and identifying landmarks visible from the top, including the Bellagio fountains, the mountains ringing the valley and, after dark, the full length of the Strip's neon. Tickets are collected at the High Roller box office inside The LINQ Hotel and remain valid for three days from the selected date. Daytime and anytime tickets are sold separately, the latter permitting boarding from midday until closing.
