Timberland lake in Jackson is nice. Not tip of the line but it is near six flags and the staff is friendly.

It depends on if you want to stay near the NJ turnpike or the Garden state parkway.
Bakers acres is a place I take my boys. Family and pet friendly.
I have also stayed in the Cape may area at two places.
Adventure bound was roomy, pool was ok, campsite was close to wildwood boardwalk.
Seashore ca
Mpsite was big. Many full time and seasonal spots taken. They have a nice swimming pond and the pool is big.
All the places above I have been to once or twice and would go back with my family and dog.
Hope that helps.
Are you wanting cape may and planing on taking the ferry across or drive over the bridge to southern MD?
