Let a gondolier "o sole mio" you down Vegas's rendition of Venice's Canalozzo. We love this attraction because it's done so well—owner Sheldon Adelson was obsessed with getting the canals just right: he had them drained and repainted three times before he was satisfied with the hue, and the colossal reproduction of St. Mark's Square at the end of the canal is authentic right down to the colors of the façades. The gondoliers who ply the waterway are professional entertainers and train for two weeks to maneuver the canals. It all makes for a rather entertaining way to while away an hour on the Strip. Outdoor gondola rides along the resort's exterior waterway are also available, weather permitting.
