Antonia,
I, my wife and son will be in Whitby from the 15th to t24th if push comes to shove I can always stow my small (3 man) dome tent in my car for you. We have an old tatty caravan at Whitby up on the cliff top near the Abbey. The camp site there will be full of folkies, but it can get a bit noisy until the early hours, not all are as considerate as they might be of other people need for sleep. You are more than welcome to use it, and as Noreen has stated lots of Catters get to Whitby

Cheers Raggy
