We went once..I'll never go back. It was a complete disappointment compared to Disney or even Hershey Park. The quality of the shows, food and parades was not worth it IMHO. Additionally, I found it very bad in the sense that there isn't much for adults to do...even with your kids, the kids go on their own for most of the rides/attractions. That in and of itself is a problem as many parents I found would let their kids roam free doing as they pleased which is tough on smaller kids (mine was 4 at the time).
Also, I didn't like the wait on line for 40minutes to get into a water pool/attraction that was kicking you out 4-5 minutes later - limited shade by the way.
The cast members are not well trained in crowd management - example - we went to the Elmo live show and waited 40 minutes to get in...the last minute louie's showed up and the CM's were telling those of us who were sitting center stage to move to the ends to let the late arrivers sit - UHHH Hello, I waited in line for 40 minutes to get a good seat how about they sit on the ends with a view of only half the stage.
Finally the Big Bird and Friends dinner was a buffet (free for all), they ran out milk, and had to be coaxed to "open up" the milk for tomorrow's show and the show was at ground level not on a stage, meaning it was constantly being interrupted by people getting up to go get their food.
It was by far the worst park experience I had in my life, we had planned on 2 days there and we drove back home after the 1st day, no point in throwing good money after bad on a hotel if we weren't staying.
