It's my birthday weekend around the time of the amsterdam meet, so i might try and make it.
before when i went out there i stayed at http://www.damrakhotels.com .. this was in december and for a triple room it was only 20 euros each (So 60 euros per night for a room that allows 3). I didn't bother booking in advance, just turned up there, walked in and they sorted us out a room.
We need to go to the banana bar... 45 euros each, drink as much as you want for an hour and if you each chip in to make 50 euros, they will do a show for you, great fun.
Found once place out there 6 euros for 2 double drinks and a mixer cause everywhere in amsterdam is way over the top with prices, like 6 euros a beer.
