Hi Craig,
Houx hasnt really changed that much dude in the 6 years since your last visit, The shower block is still there being swept out by the lovely French Pikey femmes, the bog roll they give you is still pink. The outside wash basins are still there, I know this because I saw some guy taking a dump in one last year...NICE! They seem to sell alot more grub and beer at the shop nowadays and it stays open longer.
The pitches are smaller and you can get a 2 or 3 man dome tent along with your car on the average pitch, however there are bigger ones, luck of the draw I suppose. With each pitch comes access to power although I have noticed that this can be some way away and normally involves jiggery pokery with extension leads and all that jazz...hope this helps..
later...
