I got the Downtown Minneapolis Hyatt Regency for $60 for 2/15-2/17 - I had started at $45/night. Total of $143 after taxes, etc. for 2 nights. Their quoted rate was $109.
For 1/13 - 1/15, I got the Mpls Hilton - the one near the Convention Center - for $50/night. Rated as a 3-star. Thanks for the info on the hotel list. Bluebill
