Hardcore campers don't go NEAR the bigger/ more popular sites on a BH! Look on UK campsite (link given below) if you don't believe me!
I was wondering why I go camping- dodgy week last year in Charmouth (because of the WEATHER), but a good site nonetheless; but THIS year we only went for 4 nights to Sandy Balls (the site, not the MNetter though I'm SURE she'd have us if we asked!), I made absolutely sure I didn't spend more than 4 hours total on arranging it and getting the stuff together and in the car; the weather, miraculously, wasn't at all bad, and it was by far my most enjoyable family camping experience! Oh, and I think we spent no more than 4 hours deconstructing the whole doodah once we were home (inc 3 wash loads). I'm militarily organised and I take a hanging rail and canvas 'shelf unit'.
SO why does it work for me?
-The sheer novelty value of being in a tent
-The freedom it allows the children
- Just BEING there is often holiday enough for younger kids
-The pleasure of twilight on a nice summer's evening, glass of wine in hand; exhausted, happy children falling asleep
-It's relatively cheap
-The knowledge that what you look like in the morning DOES NOT MATTER as everyone looks the same!
To me it sounds like
a) you're not really 'into' the concept which is fine, of course! Some are, some aren't and
b) you were there at such a busy time they couldn't cope AND, dare I say,
c) BHs in particular do tend to attract the less considerate, heavily boozed up brigade who by and large, also only ever camp the once, to be replaced by a different hoard next year!
The nature of camping in the UK HAS changed in recent years. The Guardian etc made it quite popular and trendy (post 9-11) so suddenly there was nothing 'last minute' about it anymore; you have to book the best sites a year in advance! The upside is you can do it in a lot more comfort, if you choose. I insist on proper loos and hot showers even if we only shower properly every 2-3 days. The best and most commendable sites keep these spotless, but- it IS possible sites like Nodes Point assume their BH crowd are mainly going to be 'one hit wonders' if you'll excuse the expression so maybe don't put in the effort for cleanliness their UK campsite reviews normally speak of.
Finally, I'd treat the concept of French camping as being a whole different ball park. I've not been but I gather standards are consistently higher etc.
