We had been planning a trip to NC & SC in September but have had to delay until May next year. We will be over during Myrtle Beach Bike week. We are planning to spend half the time in North Carolina & the other half in South Carolina. Will it be very busy during this time? We will probably arrive at Myrtle beach on the last night of bike week. Is it better to stay outside the town as I am worried about availability of rooms in the town.
