I'm looking to go away with my two adult (in their 20s) children - either a city break or, more likely a beach type holiday (or a combination of both). Would like to be near a nice beach/beaches but within walking distance of a town where we could look around and go out to eat/drink. Would be interested in a bit of sightseeing and a little bit of chilling/beach/pool time. I like the idea of Greece (but have no idea where to start looking, which island, etc), Dubrovnik area, Palma but open to other suggestions please as just don't know where to start. Resorts and accommodation suggestions would be very welcome.
