We are a couple flying into Bangkok mid September for 2 months. We have never been before but we are aware that it will be the wet season in some places. However, we want to see as much as possible! The second month we want to travel south along the beaches of Thailand, when its better weather. So that gives us the first month to travel northern Thailand (Chiang Mai etc), Cambodia and Vietnam. We would love to know if there is any advice people could give us, especially on places to avoid during the wet months!
Also, any information on routes would be amazing! (we finish our route in Kuala Lumpa)
