The gambling at Whiskey Pete's is primarily limited to slot machines. There aren't many tables and those aren't being played all of the time. The monorail runs all day until 9:45 and a shuttle runs between the 3 casinos 24 hours a day. So we quickly found our way over to Buffalo Bills. We started with a ride on the roller coaster and then proceeded to the tables. There is much more of a Vegas feel here. Everyone had fun.
