Theres no rv parking but there are plenty of trolley's that will take you everywhere.
Like Javier stated there is really no place for a big truck let alone a RV. There are plenty of places to park then ride one of the trolley rides to go around to all the places of interest like Ripley's.
I would recommend not putting an RV into there parking lot. You'll have a bad time as the parking lot is constantly busy and jam packed. There would be no way for you to turn around in there
