We went to the Maritime Museum. There were A TON of model ships there. We got there a bit late, so we couldn't check out everything, but there was a lot of stuff to look at.
Went to the miniature museum. We got there late, too, but unlike the Maritime Museum there were people EVERYWHERE. It is a pretty cool place, especially the giant model of Switzerland. It doesn't come up great in the picture because it's so big, but in person it was really impressive.
