On the whole, prices are going up. It's not that long ago that you could put £100/h as a maximum spend on AW and get back quite a long list of girls to choose from. Now, that list is getting very short. When you see average looking size 14/16 women in their 40's and 50's charging £150+ for an hour, it's taking the piss!
Part of the reason I've all but stopped punting is because of prices. I can't enjoy a punt if I think I'm paying too much. I now work on the rule that £2/minute is my maximum. Nobody is worth more than that. Especially when you can still end up having a crap punt no matter how much you pay.
It's our own fault too. We're the ones dumb enough to pay these prices. I don't blame the girls. We're just a wallet on legs and if they can get more money for the same amount of time then you can't blame them for trying it on.
I'm currently booking a family weekend break and a lot of girls now charge more for 1 hour of their time than I'll have to pay to take the entire family away to an all all inclusive hotel for the night. When I look at their prices compared to that, I just refuse to pay them that much.
