We have four kids ranging from 5-13. We all loved it so much! And my 3 youngest are girls. We were really doing it for my 13 yr old step son, and I figured the girls would be ok with it. They loved it too! I would love to see this again when we go back this year.
BUT..... I really don't know if I would do it with a 2 yr old. Maybe if I had older kids that wanted to see it, but if it's just your 2 yr old, i'd skip this time around. There is a lot of waiting in the beginning and you don't want to wait to long to go in, plus if it's hot, it's a long wait in the beating sun. Luckily we did this show early in the day ,but we were still very hot. At one point, there is fire, and the blast of heat was a killer there for a minute! I guess that depends on where you're sitting. Just sit up a little higher if you do decide to go!
Maybe if you had drinks and something to entertain her she would be ok.
