The roller coaster is great if you get the all day pass for $25. The kids rode it so much it ended up costing about 60 cents a ride.
My younger child went to the arcade while the older ones rode. We had a lot of issues with being charged for games (you load a card with tokens) and then not getting the right amount of "etickets" for the score on the game. The other problem we had was with the items available for boys to purchase with their etickets- not many items, it's very much aimed a little girls.
There were also odd numbered tokens for games so you end up with 1 or 2 tokens being left on your card ($1-$2) that you can't use for anything.
