Angkor Thum, Cambodia
New years day was spent on a boat from Battambang to Siem Reap.
Disadvantages:
Slow
No food or loo on board
Uncomfortable
Advantages
See floating villages
Get to sit on the roof - such fun
See another way of life - it is the bus so as many locals use it as tourists - it also picks up the usual packages etc
Bird life
Beautiful scenery that is constantly changing
Lunch stop at a local floating cafe
If you can sleep anywhere - a chance to sleep...
