I was attending a conference at the "next door" Minneapolis Convention Center. This HGI is fantastic in all aspects. Check in/Check out was expedient and the front desk staff were pleasant and welcoming. The room was very clean with fluffy towels and plenty of hot water. I ate dinner in the restaurant -- the soup and flatbread pizza were delicious! A 6-8" snowfall came in on my last night and hotel staff were busy shoveling the walkways and making certain paths were cleared for the guests.
If you are attending a conference at the convention center, this is a very nice hotel. Many of the downtown hotels have skyways connected, but the HGI stands alone. It's not a big deal unless its pouring rain or sleet. But I think the hotel staff would drop you off in that situation.
I enjoyed the fireplace in the lobby with its comfortable seating. It was nice to unwind with hot tea or coffee and relax. An excellent hotel and would stay here again.
