Here's few suggestions.Gettysburg National Historic Park. If you like history then you will love Gettysburg. Pa has some good state parks and there are 3 in the general vicinity of Gettysburg.Codorus, Gifford Pinchot and Pine Grove Furnace State park. All of them have electric hookups and several water hydrants in every loop. They also have bath houses and dump stations. They run about $26 a night. Assateague National park is another one we love. The NP campgrounds have no hookups but most loops allow generators. They have water and a dump station. We stayed in site C-48 which I think is the nicest.The wild horses will come right into your site looking for food so make sure you put it away.Check out the visitor center and the ranger demonstrations.
Next suggestion would be Huntington Beach State Park which is about 10 miles south of Myrtle Beach, SC. It has a mix of full hookups and water and electric and open and shaded sites.It's a short walk to the beach,they have a nice store with free wifi. They also have a great nature center and guided walks.It was $18 a night 3 years ago.Be sure to visit Atatlaya,the home where the owners of the land lived. You are right down the road from Murrle's Inlet where they have some good restaurants. Next would be Disneyland and Ft Wilderness. If you haven't been there before, you should spend a few days there. I would suggest stay right in the park at Ft Wilderness. It is expensive but worth it for a few days. We were in the 400 loop so we could walk to the landing and take a boat to the Majic Kingdom.You are also near the dog park, the Hoop de Do Revue ( reservations needed for the show0, the pool and Chip and Dale Show. You can pick up a bus in the front of your loop to go to the Animal Kingdom.If you get to Pa and want to see some local history, we are located between Philly and Harrisburg and would be glad to show you a few things. Just message me. One thing I would suggest if you like history and plan on traveling I-80 in Nebraska, I would suggest the Harold Warp Pioneer Museum. If you like history,old cars, trucks,motorcycles, snow mobiles, you will want to spend some time there. They have a campground with full hookups. It's not the greatest place we ever stayed, but it was ok for overnight. I believe it was $35 for full hookups but that included one ticket to the museum. Another place would be the National Museum of the US Airforce at Wright-Patterson near Dayton,Ohio. We stayed at Buck Creek Lake State park on the east side of Dayton. This is a beautiful state park with electric hookups and lots of room between sites. They even have a seperate beach for campers. I'll give you one more. Pipestem State resort Park in southern West Virginia. You have your choice of full hookups or water and electric. There is so much to do: golf,mini golf,tennis, indoor and outdoor pools, sauna,horseback riding, archery nature walks and 2 nice restaurants,one which you can only get to by cable car. Well have a great trip.
