Hi Synseal, that is one small sentence which should generate lots of different answers and opinions. If you consider the southern Spanish coastline, going round from the Benidorm area, thru Malaga etc and on to the Algarve there are getting on 20 sites which will take a 36 foot 5th wheel. The problem is finding space - from end December to end of March they are all full to overflowing. So, if you are content to reserve your pitch months in advance (minimum reservation for that period is usually at least one month) and then not move, you'll be OK.
