I am interested in going to hua hin general area, and wonder if it would be worthwhile riding from BKK or Pattaya? My helmet and bike gear is in chiang mai, so I would need to get it somehow as I fly into BKK from Australia. The road looks mostly freeway. Would I be able to navigate side roads much of the way with a decent gps? Are the side roads much good in this area? Would I be better off just getting a bus there and hiring a small scooter there to look around?
