Well, Casino Pier in Seaside Heights is almost a ticket only place. Same with Jenkinson's South in Pt. Pleasant. Both great places, but only a limited number of POP options. Actually, practically every place on the Jersey Boardwalk is that way. Playland in Ocean City, Steel Pier in AC, Gillians in Ocean City.
Its still a great thing that so many places like Morey's Piers, Casino Pier, Jenkinson's, Playland, etc., all offer the chance for grandparents to share a ride with their grandkids, along with french fries and milk bottle games.
The few only parks left that offer the open family environment are Conneaut Lake, Lakemont, Kennywood, Knoebels, and a few others. That is what makes all the independents so special, a place for the whole family to enjoy.
