well, I don't see how this is going to work out for you! I got a few businesses my self in the European tourist industry and I know the Thai market as well!
But, I wish you all the the best that your venture works out!
500 a bed, I would go to a budget hotel for the same price and have TV, Aircon and privat bathroom! Wouldn't be out in the sticks either. Nana and Khaosan area plenty around!
you get 60,000 a month. You need at least three staff. That's your 60,000 already gone, or you wanna change the dirty sheets and do all the cleaning yourself?
Yeah, no sweat. Either call the airline a few days before you go, or tell em at the check in counter. When the guy that assists you got you to your taxi or bus, give him a minimum 100 bht Tip! That's what he lives off!
