Me and 2 teenage girls - where to go in Spain?

[tactum]

Thinking of taking DD and her friend, both 15 away for a week with just me, not DH in August.
Any relatively inexpensive ideas? Probably looking at Spain due to flight time/expense. Budget around £600 pp but could be flexible. Would ideally like to not need a car, and would want nice beach, bars/restaurants but no wild nightlife. Probably s/c.
Any ideas? TIA

Alcudia is lovely

Ibiza is lovely, you don't have to go to superclubs or San Antonio.

I liked Santa Eulalia but Playa d'en Bossa may be more lively for two teenagers.
The beaches in Ibiza are generally pretty, the food is great, obviously there are various bars for example go to look round Ibiza Town at night.

A boat trip to Ses Illetes in the island of Formentera is really worth it.
A beautiful beach in a kind of lagoon, lots of super yachts to look at.

I've always gone s/c or b&b because I like eating out.

My recommendation is ALWAYS Andalucia! I love the Costa de la Luz and we find so much to do there. We do hire a car because we love the cities (Seville is fabulous for a day or two) but the local buses are fine and you can explore Cadiz on public transport from Chiclana de la Frontera/La Barrosa area. The best thing about the area is that the beaches are absolutely amazing. 8km of golden sand, backed by dunes and great selection of watersports available. Nice Spanish bars and restaurants with proper tapas, lively, but not nightclub lively.
