The shows are sausage parties with a few models and some sharp looking gals that work the front desk. Don't go with great expectations of sex :P
From of what I have seen on the streets: of these cities some of the hottest girls are in Amsterdam Centraal.
I got suck under a kiosk umbrella in a downpour near the Park Hotel (the old show venue) with a gorgeous Swedish girl (she put the show models to shame) and her attractive Dutch friend. Also, all the blond girls on the bicycles workin' those legs with scarves in the breeze is very inspirational.
