I'm looking for a couple day get away for the wife and myself on our way home from a week long stay in Hilton Head. Unfortunately it will be July 3 & 4. I have seen a couple threads on here stating there there has been miles long backups on weekends to enter the park. I assume that a holiday weekend would be the worst. With only one road in the park, is it worth planning a trip here, or save it for another time when we can go during the week?
