It looks to me like a resort that has hired a bunch of girls to work for them. This can be good or bad, depending on the girl you end up with and if the resort is good or not. Personally knowing what I know, if I was going to go this route I would find somebody for a guide who goes over all the time and is not tied to a resort like this seems to be...and trust me the hot girls are a dime a dozen, you will have no problem finding your own women to suit your tastes. You will probabaly run out of time before you run out of options or money
Don't know anything about them, but IMHO....Way over-priced for Thailand.
Unless it reads "companions" not companion, 24/7. Depending on your stamina and your adventurousness, you can have 3 or 4 girls a day, plus hotel, food and drinks for those prices.
For an all-inclusive catered vacation at $500/day, I'd rather go to Bali for less.
