SESAME PLACE IS 60 BUCKS NOW!?!?!
Anyway.
I used to work at the park 'back in the day' when I was 40lbs heavier, under the age to drink, and 'not a man'. So it was many years ago. The park is 75% water park, 25% dry attractions and things. There's a coaster, a stage show, a parade, a play area, and I think two or three family flat rides for the 'dry' section.
I'm not a huge water park person at all, so I wouldn't go back. But that's just me. If your daughter LOVES pools and water parks she'll love Sesame Place. Otherwise, no. Also, note that the park sells the one and two day tickets at THE SAME PRICE. We used to push this hard core. Also, local places (Wendy's, grocery stores, etc) give out discount coupons for like $10 off per ticket, or something, for single day tickets.
