Review for Treasure Island - TI Hotel & Casino, a Radisson Hotel Review For Treasure Island - TI Hotel & Casino, a Radisson Hotel Google User Oct 16 '17 at 21:05 Nice hotel. Rooms were very nice and comfortable. Large sleeping area and included a mini fridge. The casino was a little dated, the slot machines did not have the newer games as seen in other hotels. I was there on a Sunday, and tried to go to Billy's but they had a cover charge, even for guests they said. Great place to sleep but went elsewhere for food and entertainment.
