Read my post above.. You'll not find too many 'hotties' roaming the streets of either resort. Sunny beach is much bigger,but much the same. What you will find are girls who look okay from a distance in the dark, but in bright light close up, they're an altogether different proposition. most of them have not good hygene, i met one who had pussy warts, needless to say i bolted! Also the pimps control the time you get with them, see above. As already advised stick to the 'offices'. Quality may be just as ropey, but much cheaper. Most of the beauties are plying their trade, in western countries, leaving the mingers at home. it wasn't always like this, but it is now! Go give it a rip, but i'll be saying 'told you so' Enjoy the beach, the tourists and the food.
The main thing that put me off Sunny Beach, was the fact that, on entrance to the main disco, the security guys scanned everyone for weapons, this could be a good or bad thing, depending on how you look at it. But as i'd never seen that in Golden sands, i decided that it was much more cosy up there. i knew a lot of people and felt safer!
