Buy a blind fold! Fat brits like to roam / sunbathe naked. Hmm southern spain in august, it's going to be brutally hot. I wouldn't pack much. you'll eat light during the day. As i remember, the beaches right around marbella are rocky... so get some pointers on where to go for the sandy nicer beaches. If you've never been to spain before...

Travel to Sevilla - a couple cool churches, the giralda tower, one of the supposed graves of christopher columbus, flamenco dances, and so on.

Granada and see Alhambra - an amazing moorish castle. You'll appreciate the running water as it tends to be 10-12* cooler around the palace than anywhere else as a result of all of the pools, fountains, etc.

Ferry across the straight of gibraltar, to morroco and expierence a muslim culture. warning if you're female, have a male traveling companinon and stick close to him. the men are very forward and pushy trying to sell to women, and are especially forceful with blonde women. But it's a beautiful city ... quite a shock for most people ... especially westerners who's views of muslim culture and way of life come from movies.
