Hi martymod, Sorry to hear about your holiday.
My wife and I stayed for two weeks in a chalet at New Beach Holiday Park in Dymchurch Beach in July. New Beach is operated by Hoseasons and is a large park with many static caravans and chalets. It's a few minutes from the beach and has a club, shop, swimming pool etc. There are plenty of places to visit in the area as well as the ferries at Dover for day trips to France.
The prices are reasonable and we had a good time, although we spent most of our time touring. You would probably be happier there than where you stayed.
Hope that helps and hope your next holiday is better.
