BDR, It isn't that attractions make other campgrounds more fun ... nothing can compare to Disney! But as for the camp sites themselves ...
My absolute favorite is Outdoor Resorts St. Lucie West. Privately owned sites that are rented out by the owners who have spent tens of thousands on landscaping. No amenities except pools and a golf course, but such a nice, laid-back vacation. Across the street from the NY Mets training facility, 20 minutes to great beaches. Good bicycling. Restaurants and shopping nearby.
Another great campground is Outdoor Resorts Hilton Head. Not as nice as OR SLW, but still great. Nice pool, laid-back atmosphere. 1 mile to the beach, restaurants and shopping within walking distance. Hilton Head has bicycle trails all over the island.
Another of my favorite campgrounds is Ocean Lakes in Myrtle Beach. We go there several times a year. Yes, you're packed in like sardines with no shade. But you can reserve a specific site and you have the ocean at your doorstep. Constant activities, great security. Huge pool, mini golf, great campground store, the owners are wonderful. You could stay there for many days without leaving the campground. 100+ golf courses in the area, outlet shopping, more restaurants than you can imagine, lots of activities in the area.
Treasure Coast in Ft. Pierce, Fl, is also very nice.
Hope this helps!
