MrsMc82 we've just come back from a week at Les Mediterranees (first week in Sept) - Beach Garden (nb. Les Mediterrranees also have a camp site called Beach Club 5 minutes walk away from the Beach Garden).
The site was half empty (which imho is a good thing). Canvas mobile homes and tents are at the back half of the site - it's obviously the more recent part of the campsite as the trees are a lot less established, so not much natural shade (didn't view this as a negative we were out all day every day). Beach is 5 mins walk through the campsite - beach is sandy and very gently sloping (was ideal for our toddler).
Think the whole area might be a bit noisy in high season - there are lots of campsites next to one another and I think lots of them have "entertainment" in high season.
From a noticeboard near the pool, it looks like they are re-building the whole pool complex for next year.
MrsMc82 We're getting Eurostar to Avignon (they run a direct service from London St. Pancras to Avignon for about 8 weeks over summer - no changes), then picking up a hire car and driving the last 70(?) miles.
If no-one else gives any feedback on the campsite, I'll give you feedback when we get back in September.
