There isn't parking in front for cars. You can either ride the boat over from Magic Kingdom or park in the main parking lot of Fort Wilderness and catch a bus to Pioneer Hall.
Parking is at the front of the campgrounds. You will then need to take a bus to the back of the property (buses leave about ever 5 - 10 minutes and take 10-15 minutes to reach the back)
There is parking but it's at the outpost. You have to take one of three internal bus routes to the settlement where the show is.
I recommend the boat from magic kingdom, its a nice ride on bay lake. Just make sure you leave plenty of time. The ride is about 15 minutes not counting waiting.
We took the boat from Magic Kingdom. I didn't notice car parking.
If you are on the monorail, i recommend taking the boat from magic kingdom. If i remember correctly there is about 2 or three transitions by bus and parking, you will have to wait for the bus. If you have kids, mono rail to boat is the the easiest way.
