I have to say I don't really like the south of Spain it seems ‘lost’, but it would be hard to not to get excited about the chance to play on Valderama. They do allow you on but only if you start between 12 and 2 when the members are enjoying lunch!
You started by looking for an alternative to a rainy chilly weather and Morocco and south of Spain offer your best options but........ for me the most enticing base is Biarritz. On the recent French thread the following courses are all within 45mins travel.
13. Golf de Moliets, Moliets
15. G.C. d'Hossegor, Hossegor
16. Golf de Chiberta, Anglet (NAF posted some pictures recently.)
In addition there are another 3 or 4 courses in the Peugeot Golf Guide that would make good division two courses and like Chiberta are within 15mins of the centre.
The weather is definitely more variable here. Should be warm, could be really warm and could also be wet. It's odd but I've never been able to get Biarritz or Bayonne up on one of those sites that tell you the average temperature and rainfall so this is based on anecdotal evidence.
Biarritz is a great place with lots to do and it's one of the few places I've travelled to that remains high on my list of next trips.
