Review for Treasure Island - TI Hotel & Casino, a Radisson Hotel Review For Treasure Island - TI Hotel & Casino, a Radisson Hotel Google User Sep 25 '17 at 19:08 All staff extremely helpful and very personable. Hotel is an older property Are room shows its age . Casino is very nice with all the latest Slots. We did notice alot of homeless types roaming around and even watched as one of them stole items from the Starbucks located on the Casino floor . We let the MOD know about the incident and he told us it's not the first time something like this had happened. But over all a nice Property . View full site to comment or like
