Hi Bill,
If you are down in Benalmadena Costa, a car park on the left side of Paloma Park has been use3d by many motorhomes and as long as you do not arrive on market days police seem to allow overnight stays.
To find this place as you drive down to coast road turn right up the hill at the windmill roundabout. Then turn first left at the enterance to the park. Drive round keeping the park on your right and you will come to the car park on the left.
Also if you get down as far as Gib you will find motorhomes parked outside the border to the far left. We stayed overnight there last year.
I hope this is still the case as it was last November.
