Overall.. Holland is a sweet partyplace...
But one of the funniest parties in the world that I know of is:
The Mondaybar boatcruises in sweden.
23h boatcruise from sweden-finland and back..

Totally great intimate feeling... 2000 clubkids on a cruise boat with some of the best DJ's..its really ridicilous amounts of fun... can't be described.. GREAT social atmosphere, great unity... great music... people are SUPER open and nice.. and this has nothing to do with crazy amounts of

... infact, very very few out of these 2000 do any type of drug....
I rank it as equally/more fun than going to the big parties in germany/holland...
