For anyone who has traveled to Thailand: We're in our early 70s and are planning a 21 day trip to Thailand and Cambodia, flying into and out of Bangkok. We have never been to South East Asia have some questions about the logistics and whether our plan even makes sense. We plan to go in mid January, 2017. Our itinerary is as follows: Siem Reap, 4 nights; Krabi, 5 nights; Chiang Mai, 4 nights; Sukhothai, 4 nights; Bangkok, 4 nights. We think we should fly between Bangkok and Siem Reap; Siem Reap and Krabi; and Krabi and Chiang Mai due to the distances, then bus between Chiang Mai and Sukhothai and on to Bangkok. Is our transportation plan sensible? Are the locations too far apart? Is this a good overall plan to experience Thailand & Angkor Wat? Is this even doable?
Any suggestions &/or advice would be appreciated.
