I'd start with a walk/run/bike around the trails of the Mississippi. Stop in on the northeast side at one of the restaurants with patio dining on St. Anthony Main. Walk across the Stone Arch bridge for the best view of the city, and to check out the lock and dam. The chain of lakes is similarly fun, and you can rent canoes on Lake Calhoun or go to the beach, which is an honest-to-God sandy lake beach right in the city. Lake Harriet just to the south has a bandshell with concerts that are free and fun. (Note that our alcohol laws are more restrictive, so just do what Americans do and disguise your drinks.) If you want to go even further afield, you can head out to Minnehaha Park and check out the waterfall and hike the trails along the river. There's a fun restaurant there too with great seafood that's flown in fresh, but still somehow not that expensive. It's called Sea Salt. Mall of America is sadly still the big tourist trap, but it's truly just a big mall. Kids may have fun with the Lego store and/or the mini theme park in the middle of the mall. There's no sales tax on clothes in Minnesota. The Guthrie Theater is a competent theater company in a architecturally stunning building. Even if you don't go to a show, make sure you check out that big blue building on the Mississippi. The Minneapolis Institute of Arts and the Weissman Art Museum at the University of Minnesota can be fun too. A free and outdoor alternative is the sculpture garden in front of the basilica downtown. You can check out the spoon bridge and cherry sculpture, which is pretty iconic Minneapolis. The basilica itself is - probably surprisingly - the oldest in the country to be designated a basilica, and it's worth a look inside, although the British have more impressive homegrown examples. Still it's free and just across the street. The Walker Art Museum is down there too, but I tend to find their collections unimpressive. Modern art just doesn't get me. Walk down Nicollet Mall when you get a chance, and check out the downtown core. It's a pretty modern city, and there's not really an "old town" to speak of, but it can be fun and crowded in the summer. The North Loop neighborhood is where a lot is happening these days, centered on Washington Ave. N. and 1st St. N. There are very high quality restaurants there, some fun dive bars, and pretty much anything in between. The best restaurant may be Spoon and Stable, if you can get in. Freehouse is a good place too, and one of my favorites. For a no frills, super friendly dive bar, Cuzzy's is hard to beat. For that fancy cocktail after the game, Marvel Bar is awesome, if you can find its hidden door. The good news is that these are all super close to Target Field. 1st Ave. N (avenue, not street; the former are north-south, the latter east-west) is the party street. It can get a little sketchy late at night, in my opinion, but before the game it's great. If you're into clubbing for whatever reason, maybe because you hate yourself, that's probably the place to be too. As to your transport situation. If you'll be downtown, there's lots within walking distance, but you should also check out NiceRide shared bikes for quicker and further reach, and the light rail if you're going to Mall of America or Minnehaha Park and falls. If the weather turns bad, poking around the skyway system in downtown can be fun for a little while. Rental car will make things easier, but parking downtown isn't terribly easy. I'm sure I left some stuff out, and someone else will have to fill in the St. Paul side of things because I'm a Minneapolis partisan. But if you have any questions, ask away. I hope you really enjoy your time in Minnesota.
