I thought I overheard someone saying that the shop in the village was going to start renting pads but I may be mistaken, think the shop details are in the guidebook? Depending on what time of year you're going the campsite may not even be open. I don't think it was open when we were there in November, which is why they were tolerating some people camping in the main car park in their vans.
I can't remember if it was shut because of the time of year or for some other reason, so worth checking.
