I'm pondering going to WGW

I'm pondering going to Whitby, as I've never been before. Only thing is that I have no ticket and no accommodation booked. Can I blag floorspace/bed share(!) with anyone? Or would it be more hassle than it's worth? Will I miss out on much not having a ticket? (And what /can/ I do without one?) I'm pondering going because I know loads of people that go ona regular basis and it sounds like such fun... but what actually happens. Chemicals are not my thing, though I know it goes on and don't mind so much being around it.
