Planning the trip

Before starting my job I'm going to do a trip for one month in southeast asia starting next friday. I'm going to start in Hong Kong and Macau where I'm going to stay 10 days, then 10 days around Vietnam, 2 days in Cambodia (Siem Reap and Angkor) and in the end 5 days in Bangkok. From there I fly direct to Holland to start my work there. Most of the trip will be by plane (10 flights) and the rest by bus and boat.
