My wife and I are spending 4 days in Minneapolis without the kids. We want to hike, bike, raft (already have some ideas from the Forum that 1 hour north of the city), but also do some shopping. For shopping, we prefer a combo of art galleries, boutiques, and upscale areas. As an example, we'd probably not go to Mall of America. We plan to stay smack in the middle of downtown (Kimpton - The Grand) so we can utilize the rail system and enjoy the restaurants. Any hidden gems or advice for either 1/2 day trips, things accessible using the rail system (or Uber), and shopping areas would be greatly valued.
