Crossfire Lan noobs + AVB Fans

OK, just ordered my ticket for Armin Only 11/11 (22.00 to 7.30) in Rotterdam. What I want to know, all you noobs that went to the crossfire lan. Where did you stay and was it nice, need suggestion somewhere close to @ Rotterdams Ahoy (where its happening). Also how might i get back from said concert to my accomidation ie taxis on sunday that early ? Or just general info i guess, just post anything you think useful, places to visit etc anything basically.

Thanks :)
