Youth hostels around TP & BP ?? (UK)

Hey Guys!
I'm looking for cheap Hostels around London and Blackpool Pleasure Beach. Me and some friends are going to do a tour around UKs parks, and we were not yet able to find some good youth hostels in this area. And as some of you are from UK, i thought maybe somebody could help us. Would be great to get some tipps from you [;)]

Looking forward to some nice answers

Heh, after seeing that movie this weekend I just do not see me making any trips, to any Hostel's, in the near or distant future.

I know of a travel inn a couple of miles away from thorpe. In cobham or somewhere. Pretty cheap but relatively good. Im not sure about Youth hostels though. Sorry
