If you have booked a partial hookup site, then there will be LOTS of tent campers around you.
The comfort stations are wonderful!! My favorite is Loop 1500, very central in the campground and right across the way from the Meadows Trading Post, campfire, and bike barn.
Loop 2000 is kind of remote, but does tend to have larger sand pads if you have a large tent or several tents and need more room.
You will have electricity and water. Bring at least a 40 ft outdoor extension cord and a couple of power strips for anything electric you want to bring.
Bring an electric fan to run in the tent during the day while you are gone to combat the humidity. The evenings should be comfortable.
Waterproof your tent well and bring some type of "dining fly/screenhouse" to put in front of your tent as a mud room to remove shoes/raingear before entering your tent. Also a great place for chairs to just sit and relax outside your tent.
Bring a toiletry bag for each member of your family so that you can all take your showers at the same time.
Bring some cheap painters plastic to put under your regular groundcloth and dispose it at the end of the trip. The sand gets nasty and that keeps your regular groundcloth and the bottom of your tent clean.
Campfires and Tiki Torches are not allowed at the campsites, so if you are doing any of your cooking yourself, you will need to use a propane stove, an electric skillet, a crockpot, microwave, or charcoal in the grill provided.
There are garbage cans dispersed around the loop, but not necessarily one right in front of your campsite, so bring a few large garbage bags so you don't have to walk to the trashcan for every little piece of garbage.
Hope I've been helpful.
