Well, there are 2 options. You can drive over to the TTC and catch the boat over to FW - or - you can drive your car over to FW. Park in the front parking lot and catch the bus to the marina. There is NO parking in the campground, except for a few spaces at the Meadow Trading post and that is only for 15 min. They don't really want you driving your car around the park, they would rather you use there transportation.
