not really lah. i go on really budget trips most of the time.
live in simple plcs (must have a/c, own toilet n hot water). food i
will usually risk eatg from hawkers.
thou i spent bout 2k for this trip. most of it was the airfare.
food n water in cambodia was a health risk so i stuk to beer n
restaurants. 
rest of the $$ went to day passes. tuk tuk trips. buyg t
shirts.
