Well, it may be crazy in this SE Asia, but I just wanna thru the idea and questions, looking for some advices. My team will have a motorcycle trip from Vietnam (HCMC) thru Cambodia to Chiang Mai 1st week of this December. But I just can join them small part of the trip. I have to come back HCMC by 04 Dec. There are some options for me now: 1. Fly all the way from SGN-BKK-CNX-BKK-SGN. Rent a bike in Chiang Mai and ride around for some days, before doing the MHS loop with my team on 03Dec. 2. Fly and ride. I will get the flight SGN-BKK, spend a night in BKK. Rent a bike in BKK and ride to CNX early the next day. - Riding from BKK to CNX within a day is doable, right? If so, I prefer the option 2. - Concern: I don't want to spend one more day to ride from CNX back to BKK, to save time as I have to head back HCMC by 04Dec. So, some questions come up: 1. Anyone wants to ship his bike from BKK to CNX (01Dec), I can ride it for you there. I had some offers like that during my trip in the US last year. But don't know it applicable in SE Asia. Anyway, just ask. :-?. 2. How about the bike rental agents in BKK? Will they offer the option that pick-up the bike in BKK and return the bike in CNX? Thank you very much for your comments and recommendation.
