I did it for the novelty but it was NOT a good SP experience. It's fun to window shop but the sex is 15 minutes worth on a small bed or massage table, very functional and mechanical. There are likely much better ways to hobby in Amsterdam so if you want an actual GFE, avoid the window girls and do some deeper research into hobbying in Holland. If you just want the stamp in your passport that says "Amsterdam RLD", then yes expect to pay 100E give or take for bad sex, and make the most of it! Don't forget the Rijksmusee. One of the very best on earth. Bon voyage.
