PS Daz H: I have been thinking of buying a campervan recently, exactly as you say - but with petrol prices as they are ... it's going to cost me £5,000 for secondhand T4 or similar, god knows what on tax and insurance, and then probably £100 petrol to the Lakes and back.

Off-peak return on the train is £80 - cheaper if you book in advance. OK, maybe a room on top if I can't be bothered camping, but still ....
