We have stopped there a couple of times, its a good site, yes it is popular but it is in a good situation, with good facilities and you can walk to the beach.
Thanks for the video, but after the first minute I'd seen enough! Just the sort of site I avoid at all costs, vans and tents so close, you could lean out of your window and shake hands with your neighbour. What happened to fire regulations that are enforced at Caravan and camping Club sites? Imagine if one of those units caught fire in the night...disaster! Its only saving grace is its close to the beach, but at what price. I'm sure its very popular, but not for me thanks.
I`ve never stayed at a Gypsy site so I can`t comment, but Woodhall Park is a very popular camping site and has won many awards over the years, it does unfortunately get very busy at peak times.
