Wishy,
My Son is in the same boat, and I don't mean a ferry! He (and I) desperately want to go, but with exams, his racing etc. etc. its near impossible, but I know that I'm going to have to give in and maybe do a flying visit like we did a few years ago, over night Friday, back Sunday night.
Three things occur to me. 1. Roughly whereabouts are you based, for a quick collection/meet en-route., 2. What campsite are you on, and 3. What are the chances of getting another camping pass?
There is a small, and I mean small, chance that I can finally persuade a mate of mine to take his plane, but that really is a long shot!!
If I can help, I'll be delighted.
