When we went w/ dd (17mo and 28mo) she loved EVERYTHING we did... basically anything she could ride. In December we visited again (dd is now 6.5yo!!) and ds turned 2yo while we were there.
I have two VERY different children. Dd has always been shy..but a daredevil physically. Loves any kind of ride, swing, playground, etc. She couldn't wait until she was 3yo and could ride the Grover rollercoaster at Sesame Place (we live locally).
Ds on the other hand, can't stand swings, hates carnival rides and freaks out if he isn't in total control. He does however charm everyone he meets and isn't shy in the least.

Go figure??
