The Eros guide girls are mostly, but not all, agency or high end girls. If you call her, be sure to ask first, if the rate is all-inclusive, and if there is a "show-up" fee or a flat rate. If they are evasive, they are agency upsellers. They also will insist on your room number, or home address, but don't give that to them, its very risky. Meet them in the lobby, or at a Starbucks.
