We didnt know they were going to be there. Anyway when we went to the Kartrite my wife and I saw another friend of ours with their kids who happen to be from NJ too. Also before the Summer Starts they are going be opening the largest Legoland in the US in New York and will be under 30 minutes from the casino and waterpark.
Killer Arcade, they show movies and other activities like 80s Nintendo Galaga Tournament. The place is pretty new and has a few things to do besides the waterpark.
If you live in the NY, NJ, CT, Eastern Pa, Maybe western Ma and have kids I would suggest going there. My wife, my son and I went with two other Families to the Kartrite Waterpark resort in Monticello New York for President’s Day weekend.
