Review for Treasure Island - TI Hotel & Casino, a Radisson Hotel Review For Treasure Island - TI Hotel & Casino, a Radisson Hotel Google User Sep 20 '17 at 18:33 Came here for our anniversary. Guest check in, although we had a bit of a wait, went well. We were able to get an upgraded for our special event. All the staff seem very friendly. Rooms are clean and spacious. Pillows could be a little more firm. Way too soft for my liking. Overall, I would recommend TI for your stay. View full site to comment or like
