Hard to beat Peurto Banus (Marbella) if you have the money... Little bit more expensive than your average Spanish spot but worth it... Some of the finest ladies available...
Friend of mine has a villa there and we pop over twice a year..
No prob getting coke there.. Ask any of the girls and they will get ya sorted...
Check out the navy bar and the playboy club for girls.. Both bars where you can drink with the girls before u partake..
