I would echo the guys saying find a hotel by the Mall of America. Most of the hotels near the Mall have shuttle busses going back and forth from the hotel to the Mall, so you don’t even have to drive again after you get to the hotel.
Hotels I’d recommend looking at:
The Grandparent of the Year Option – Radisson Mall of America! Nice hotel, very close to Mall, and has the attached Waterpark of America that the kids will freak out over.
Bonus: Hotel guests get exclusive access to the water park every morning from opening to 11:00. Totally awesome perk because then there are no crowds and no lines for anything for 3 hours, so the kids can go nuts.
Really cool modern hotel with great Mall access: Radisson Blu. Literally attached to the Mall. Upscale option, very modern, but when I’ve stayed there there are still plenty of families with kids staying.
The Crowne Plaza is decent, so is the Embassy Suites although the Embassy is very close the airport/flight path. Really, any of the airport hotels or any hotel near the MOA will do.
As others have said, don’t worry about downtown before/after a game. The light rail station is literally attached to Target Field so you don’t even have to walk a block to get from the train to the stadium.
After, there will be crowds and lots of police presence both downtown and on the light rail for hours after the game. You’ll need to be a little patient in waiting for a train to go back to the MOA, but that’s a small price to pay.
