I mostly go to shop. Pretty good deals on some thing compared with Calgary.
The Lewis & Clark museum is nice, a mile or so down the road is the big park. Darn if I can remember the name, Springs something. It is beautiful & along the river, has a fish hatchery you can wander around & used to be able to buy pellets to feed the fish not sure if you can still do this. The park is also home to the world's shortest river.
If your travelling with older kids there's a nice pool with lazy river & surfing thing. It's downtown sort of.
We've stayed at the Crystal Inn a few times, it's newer, up on top of the hill by the airport. Pool , fitness, free hot breakfast.
Not sure if Golden Corral is re-opened yet but it's a good place to stuff your face.
