We did it with our 5 and 8 year old grandsons and did the baby sitting as Carol suggested a couple of times with great appreciation from our kids. Must do the Parrot Ville, they also loved the butterfly farm and the plane watching. Also a hit was the floating park at the end of the boardwalk in Phillipsburg, they were completely tuckered out but loved it. Since it was calm when we were there we spent a couple of days at Kon Tiki where jet ski's were rented. Great memories!!!
