Overall, the provision of motorhome aires is decidedly sparse around the Alicante area. It is a bit better further north but not as comprehensive a France and Germany. My motorhome aire guide book has 170 pages for both France and Germany but a mere 24 for Spain. If the authorities don't want 'wild camping' then the solution is better aire provision. Motorhomes are self-contained and don't need all the 'bells and whistles' of a full-fat site. A firm flat area, fresh water and somewhere to dump grey and black waste. It doesn't require major investment and can be provided at €5 - €10 per night if not free, as many in France are.
