No decision has been made yet on whether you will be able to go back and forth to your RV from the Festival. I think it is too restrictive if they don't let you do this. The shows go on for 12 hours, it would be conviernt to go back to your RV especially if you have children with you.
I would love to bring my parents to the fesitval for a fun-filled weekend of camping and great Country music. However, my father is 74 and will not be able to stay in the festival area all day. The "no in and out" rule would make it almost impossible for us to enjoy the festival.
