I have to say that the last time I visited Castles N Coasters was a much better experience than the time before.
This last time I went with my kids for my son's birthday, CnC was cleaner, the employees were friendlier and more helpful, and we had a better experience overall.
There are coupons in the Entertainment Book, and CnC isn't exactly cheap so definitely use those if you go. The arcade is nicer, with more modern selections but also keeping the classics upstairs. If all you want to play is modern arcade games, Dave and Busters is probably a better value for the money, but we were pleased.
I really wish they would expand, as I have heard rumors of them taking over some real estate that belongs to the dying mall nearby.
Also wishing they had an elevator inside for wheelchair/stroller accessibility.
Still, for a city that doesn't exactly have a "theme park" this isn't a bad place by any means.
