No it's definately mahaka on mainland spain. I've seen it before and remember it is not spelt how it sounds, Ive even looked at a map of spain to no avail!! I know it exists!! It's driving me crazy now!
I lived in Almeria for many years and am pretty sure you mean Mojacar the phonetic pronunciation is pretty much as you spell your mystery resort. It;s a small white town with both a beachside area and a hillside town which is mostly owned by expatriots
