We are two families with 3 teens/tweens between us. We will be spending a week in Sitges (outside of Barcelona) and have 3-5 extra days to spend before we fly home from Barcelona. Thoughts on taking an overnight ferry to one of the islands and back? Ideally, we would spend 1-2 nights on the island. Definitley overnight at least one way, and probably high-speed the other way.
Thanks!
