We were just in Disney at the beginning of last November and stayed at Fort Wilderness. It was COLD then. It was the start of the Christmas celebration and the parks were crowded.
It will be hot and expect a rain shower daily around 2pm. Doesn't normally last to long.
When staying at Fort Wilderness you shouldn't need a car. To get to the Magic Kingdom take a internal Fort Bus to the docks and take the boat over. All other parks take the internal bus to the main bus stop and then take a bus to whatever park your going to. Also the internal buses will take you to the pool, horseback riding, restaurants and other attractions in the Fort. Having to take two busses does add some travel time.
When we first looked into going the campground was full. I started looking at other campgrounds and the issue of driving to them was the cost of parking. Daily parking at the Magic Kingdom was around $30. You then take a tram to the transportation center and then a boat to Magic Kingdom. A travel agent on this forum messaged me that he could get us a spot in the Fort and he came through with flying colors. If you need his info PM me and I will forward it along to you.
Fort Wilderness is a very nice park and if we ever go back would stay there again.
Have a great trip!
