Go through the reviews, people will mostly comment on whether 'favourites' were provided and if they required extra cost. If you have a very particular favourite, ask the escort via PM or call AND when you arrive (before you pay her). Most top escorts provide all their favourites as advertised, or will explain when something cost extra. However, a lot of escorts list loads of favourites on the website and do not provide them. So you'll have to keep this in mind.
