Dear all, Any updates on this? I am on MHS loop and wanted to travel by motorbike from Mae Sariang via R105 to Mae Sot for a 2-day-visit and from there down to Umphang via R1090 for another 2-day-visit, then back to Mae Sot and from there to Tak via R1175 (if this is not possible, then via H12) and to Sukhothai, Si Satchanalai and back to Chiang Mai. Do I need a Thai guarantor in Mae Sot and are there any serious problems for normal tourists? Thank you in advance!
