"Went in car to Benidorm today and checked out sites. First I called at Albir and vans were being turned away from Cap Blanche, also the Aire on the seafront road was packed with vans, not much space between them. There were several vans parked on the beach by the river in Altea. At El Raco vans were parked on the main road outside site and I didn't see any spaces on site. Arena Blanca car park was packed with about 10 vans, and La Toretta also vans on Car park. At Cala Fine...strat beach vans were parked on a car park despite clear signs forbidding motorhomes. I also saw vans driving around the area looking for spaces. I didn't go to all the sites and there may be spaces on Vilasol and Vilamar (around 30e pn short stay) but my gut feeling is that all sites in the area are full. If anyone is on their way to this beautiful part of the Costa Blanca I suggest checking with sites before you arrive."
