Well I dunno about a triple room, but the bed I had last time was massive! Easily big enough to sleep 3 peeps ;D Depends how cosy you wanna get with your travelling companions!
We're all staying at the Crowne Plaza, why don't you ask them? Or I think that Jury's Inn gaff might do triple rooms, but it's a bit farther out. Or try a Travelodge or Premier Inn thingy, they do family rooms?
OH YEAH, flights are booked and we have a room at the Crowne Plaza, me and Geo are on our way. It's gonna be a ROCKIN' good day, It'll be nice to meet everyone and put faces to names, really lookin forward to it ;D
