Is there an upper age limit on this trip? i'll be 41 in 2008 but i'd still love to go and with goin every year since 1990 i know central Amsterdam like the back of my hand(including the red light district lads).There are plenty of campsites outside Dam but then you're talking expensive late night taxi journeys from Dam to the campsite, decent quality budget accommdation can be found right in the middle of the action and with a large group booking you might be able to negotiate a discount with a hotelier,just a thought anyway later
