Np prostitute is worth 300-350 an hour ------------- I don't care what nationality they are.
apparently the UK and Italy is not short of mugs who disagree - some of them can run countries or score goals without knowing when they're being had
I doubt you would get a classy girl in Rio for a pittance -------- but I have never been there, hotels too expensive for me.
Rio is too big and varied to generalise. Depends what you mean by classy - classy women don't work as prostitutes generally. But classy in the sense of well-spoken, not a thief, good looking, these aren't governed by price. Speaking English helps them do well in the tourist market as it does in any job. The top parlours like 4x4 are a Disneyland of attractive women, striptease, relaxation rooms, two bars, a restaurant, a firemans pole, a chat bar where you can drop in without changing out of your suit, and rooms charging according to the facilities. You just stay as long as you like and pay your tab on the way out. Easy to spend a lot, especially with multiple sessions, duos etc. All conducted in a very civilised atmosphere and the bill is rarely padded - just expensive.
But there are plenty of 'programma' girls who do it for a short time to see them through temporarily. Some end up respectably married to foreigners (I get an email from such an ex occasionally - she's now in Paris), and there's also girls who play foreigners for as much as they can get, including alimony. It's 50 times as complicated as AW and the risks of getting skinned higher. But the place has big attractions, even at today's exchange rate.
As I've said before, you should avoid hotels there if you can. Renting an apartment is relatively cheap but still dependent on things like whether you have taken time to learn the local scene. IMHO Rio is no plug n play destination. A couple of months studying the relevant ISG boards and other homework is recommended.
