Holiday destinations?

We want to go on holiday with our teenage twin girls during the first two weeks of july, it will be the first time that we can go out of term time as they will have just left school. we want a place with nice weather, near the sea but with other attractions such as markets and shops etc, we dont want them getting board as we have done that and its not nice! also we dont want to go to a place that is touristy..nightclubs, cheap lager and all day breakfasts etc are definately out! if you have been somewhere recently let me know the details.many thanks

Try a cruise around the med island cruises spring to mind.remember with a cruise most everything is included..they dep from palma majorca no worries and the girls will love it.
