Bunch out there, just search "Myrtle Beach Resort", the larger one will be more accommodating. Some have offsite lots to park trailers... We have always stayed in a house, so good luck on being up front... just avoid MB downtown. They reversed the rulings a few years ago, but the cops in MD are still forced to act like asses by city council. Try looking in North MB or Surfside. Good luck, and if u see the Army camo bike, be sure to wave!
