Did the crew hotel not give you a leisure rate? The crew hotels we have there show leisure rates below $80. I know this depends on availability, and yes, if you go to the website the hotels are over $200.
Try Radisson Blu Mall of America phone 952-881-5258 and Best Western Plus Bloomington phone 952-854-8200. Best Western says yes for shuttle, Radisson says no, shuttle operated by hotel-that statement does not make since.
