If it's a punting trip, forget Amsterdam, why is your head telling you this? as the others said it's just a commercial tourist trap.
Germany is the one, either Berlin, Frankfurt, Cologne or Düsseldorf would be recommended. Wankings our man on the street scene, It's legal or tolerated, KurfurstenStr has a lot of choice, but November might be a little chilly for alfresco shagging.
Artemis is pricey but the quality of the girls is 100 times above a street hooker, you can spend 18 hours at the club, and no need to rush into a session.
Cologne is another good option, you have Pasha, take a walk around the 7 floor laufhaus, and see who you like the look of, go to Samya, this is a ideal club to visit for a first time visitor to the German saunaclub scene, as it's a laid back club, less sharks, and a no approach policy for the girls.
Frankfurt has a number of clubs to check out, if you like young fresh girls go to Oase, for the slutty tattoo fake boobs go to Palace, Sharks is also a good option to try, or check out the RLD down town, there a some laufhaus you can wonder around.
I will be in Düsseldorf on 11th then Berlin 12th-13th, going to Insomnia again on Thursday.
