Just a quick mini review...we went on last Friday. The park was clean and the staff was friendly. The rides were about what I expected, a few steps above your typical midway rides, but a lot (5?/6?) smaller "coasters" that really catered to the 5-12 crowd. My daughter (age 6) absolutely loved it. She was also really impressed with the "mini-land" section, which kind of surprised me.
The park was completely dead though...all rides were walk on, with several ride vehicles going out with no passengers. This was great in most cases, as we were able to ride and re-ride without leaving our seats. It was only a problem on the "Chi" water ride, as there were no people to spray, or get sprayed by. Being the only ones on a giant river raft felt kind of lonely. The ride itself isn't much fun without that interaction.
We both liked "the dragon" the best, as it provided a fun dark ride and mini coaster that was just enough thrill factor for my daughter. Flight School was really only fun in the front row, and that being said it was extremely bumpy. It knocked me in the head constantly. The Spinning pony ride was probably the most thrilling ride in the park. That 4D movie was cute, but the "effects" were rather lame compared to Disney's attempts.
Overall I'd rate the park a 8 for kids under the age of 10, and maybe a 7 for slightly older kids. Kids in their teens will probably want to go to UOR instead.
My real question was, how can a park this large survive with so little turnout? How in the world did they find funding for a second hotel? I would be curious to see what their profit margins are on this park, because I'd be surprised if they weren't greatly in the red....of course this is my impression based on going on a "school day" in what is still considered off season. The park is really in the middle of nowhere too...I can't see too many out of town folks venturing out.
