cjam, wasn't addressed to me but I will try to give you an answer, if you are good about managing your money, you will have no problem having fun and putting some money in the bank, you could probably share a accommodation for around 400 to 500 without a problem, you can buy a little moped for $1000 new, if that's not your style, taxis are dirt cheap, to dry clean a pair of pants, about .70 cents, beer is about one dollar, mobile phone bills for me run about 50 dollars per month, food is cheap, easy to go out and spend less than $7.00 per person which includes lots of beer, if you net $6,400.00 that still leaves a lot at the end of the month. Also, a coach ride to the nearest resort from HCM is about $7.00 for the four hour trip, when you arrive, most rooms are between $4.00 to $60.00, three course meal for $6.00. Hope this helps.
