I personally avoid VS girls. There may be the occasional genuine article but they are mostly fake profiles with nabbed pics. AW still has its fakes but it's usually more reliable.
Haven't been to one for a while. When I did I wouldn't travel far and would go with the expectation I would be walking. The shock was the few I saw the girls looked pretty good, no need to use fake pics. The not shock was they were all crap and pretty much did nothing, and it was usually £20 extra for everything, you could easily have had a vanilla 30 mins for £200.
