We went last Friday - DH and I, two kids 8 and 10. Kids LOVED it. We liked it too, but the heat was BRUTAL. Had to arrive before 4P to get the cheap tickets - we arrived at 3:45P. It didn't cool off until 6:30P or so. They try to manage the heat with misting fans for the lines, a/c for some of the lines, etc., but it's just really, really hot. Park was clean and the rides were fun. We only saw one show - the Country ice show and it was very good.
The park is small - so not much walking. It was fairly crowded - pretty long wait times in the lines.
I'd recommend it - with the cheap tickets, anyway.
