For a bunch of 30 year olds who like to relax, eat, drink, dance, go to the beach, which would you recommend?????

Cadiz. Relaxed -- great beaches, great food.

Marbella.<BR>I always got the impression that was more nightlife-y. Also, if you're interesed, there is a good casino that you can take a cab to.

For your age and interests, I'd choose Marbella-plenty of bars and nightlife. And the nearby jet setters', models' hang-out yacht harbour of Puerto Banus rocks until the early morning hrs.-quite a scene, fascinating people watching too in high season. Beaches around Cadiz are prettier, but Marbella has a more cosmopolitan, int'l edge. Estepona is quieter, with self-contained resorts-better for couples.

Have a home in Estepona and agree that Marbella would be by far your best bet....
