Was here for a bachelor's party a few ago. Here are the quotes and prices we got from the plethora of hosts.
One bottle ($4-500) per three people and with generous tipping of the host. Another quoted the same ratio but added their own sixty per head personal fee. (WTF?!??)
I found the best way is to get as many bids as possible and do the ol' fashion negotiating and try to bring that bottle count down. I found the larger the party, the more hosts were willing to work with you. One told me that they each usually could have about four groups each night, so of course they wanted the biggest damage possible.
My recommendation is to get a table inside during the summer or by the pool. . good luck with all the ghetto Asian girls.
