When my kids were younger, they really enjoyed going to Travel Town and spending the day. They loved running around the trains, looking at the old museum like pieces. Sitting in them and eating there.
We adults were just happy to let them out of the house, run around, get exercise and watch them enjoy themselves!
Now, it's been handed down to my nieces and nephews. Now they love doing the very same things my kids did when they were younger! They run around the big trains, they look at the old sample museum sized pieces, they have parties in actual trains and can just be themselves.
I really recommend kids come and play here.
