We used DoubleTree by Hilton Minneapolis Airport as the Room Block for our wedding this April. The rooms were clean and comfortable, but we did have a few issues (poor water pressu...re in shower, multiple problems with key cards not working, missing padding on the bed for a baby). We also had some weird issues with the reservations where guests who requested a handicap room were not able to get one, or one of our guests was told they had checked out of their room when they hadn't. The staff was so friendly and tried hard to resolve every issue, but there were definitely some organizational hiccups.
The food in the restaurant was yummy, but service was definitely very slow. They only had 1-2 people working at a time, so when guests wanted to have a meal or visit the bar, we had some trouble with long waits. They also told us after a full night at the hotel bar that the drinks all needed to be put on one tab, and we felt a little rushed to clear out at the end of the night because it was just too much for one staff member to handle. That being said, they truly did work hard to accommodate our big group and it all worked out in the end!
Overall, the hotel was clean, reasonably priced, and in a GREAT location. Having shuttle access to the airport and mall absolutely made our wedding a fun-filled weekend! Unfortunately, if you are considering using for your wedding or an event, I would expect delays in responses, poor communication, and a few hiccups along the way. We had a lot of random issues come up with things like guests not receiving their vouchers for breakfast or pre-approved information cards that we provided to the front desk. If you're staying for any other reason, I don't see why you would have any issues. It's a good hotel with nice staff and great cookies!
