Disneyworld area RV parks with shuttle?

All DW attractions can be reached via the free Disney bus transportation that departs from the Fort Wilderness Campground near the entrance of the campground. From your campground loop you catch a bus that runs through the campground and then you get off at the campground entrance to transfer to the bus of your choice. But, since Universal Studios is not a Disney attraction I never recall seeing a shuttle from Fort Wilderness.
