I tent camp at Ft. Wilderness every December! October is definitely not too cold!!
Definitely have a ground cloth under your tent. I also have a sheet of plastic inside my tent. I also put a sheet of disposable plastic under everything and just toss that. The sand pad can get gooey and messy when it rains.
I bring a rain shelter and place it in front of my tent to have a place to sit outside my tent. I don't put anything extra over my tent, but just waterproof it very well with seam sealer and a spray-on fabric sealer.
Folding camp chairs are a must.
Individual sets of toiletries for each person, so you can all shower at the same time. I use a daypack with my toiletries and a change of clothes. I get it ready the night before and that is the only thing that goes in the tent with me. I can grab that quickly and get to the comfort station for that early morning bathroom run, then around the corner to the showers and get dressed.
Air mattress and electric pump.
Sheets and electric blanket. (Sew the bottom fitted, top sheet, and blanket together at the foot, so the top sheet and blanket stays put). There is nothing worse than realizing your feet are sticking out in the cold
Power strip and a minimum of a 40 foot electric extension cord.
Alarm clock
Cell phone charger
Camera battery charger or docking station
Fan (even in cool weather, open up the tent during the day and run a fan) Gets rid of the humidity/moisture you create at night.
Shower Shoes
Quarters, Laundry Detergent, Dryer Sheets
If you are driving, a mini-fridge is a good idea.
When I drive, instead of clothes in a suitcase, I use those plastic drawer units. They sit upright in the back of my pickup truck (covered) and I just open the tailgate and get stuff out of the drawers. Keeps extra stuff out of my tent.
When I fly, I actually bring an extra tent for my stuff.
Battery operated lantern and hook to hang from inside of rain fly.
Tent stake mallet
I don't cook at Ft. Wilderness, so can't give any advice about that.
However, the first boat to Contemporary runs at about 6:45 am, so I usually grab that to get my hot chocolate, banana, and bagel at the Contemporary Food n Fun Center
