Edited OP.
Legoland was pretty disappointing. They claim two floors of fun, but the first floor is simply getting tickets. It was MUCH smaller than we expected, and cramped. The kiddo still had fun, though, and the exhibits were pretty cool.
Top Golf was fun. Boyfriend is the Kitchen Manager for a BigShots Golf that is getting ready to open here, so he wanted to check out the competition.
Went to the Science Center at Union Station, and kind of wish we would have done that on Saturday instead whenever we had more time.
Overall, KC, once again, didn't disappoint.
