Hi
I would recommend the Sardinia holiday, that I went on last year. It was a good mix of relaxation by the pool or beach, plus a few excursions to the nearby towns, archaeological site and a vineyard with short travel time to get there. There was also a coastal nature park, which you can wander round a few times and explore only 5 minutes away (walking).
Its a good intro to see if the 'Escape' holidays are what you want or you want to do more with a full on tour.
I have done three JY holidays so far - Sardinia, Athens and Corinth Coast and Discover Sicily and would recommend all of them. I like to mix and match tours and relaxation. Two more pre booked for next year - Andalusia in May, and then my first long haul tour in October to China and Hong Kong, both which I am looking forward too.
