For people who have been there, done that with Mykonos and Santorini, a stop at the Greek island of Skiathos is a welcome change. The Aegean island, located just 30 miles or so from the mainland, is still touristy; the jet set made it a playground in the 1960s. But once you get to one of the island's many beaches -- there are 60 to 70 along a 25-mile coast -- you'll see why it remains a popular spot for holidays.
Only smaller ships stop in Skiathos, and even then, cruise ships tender to shore. The call is usually billed as a beach day, but if you're avoiding the sun, wander around Skiathos Town for some shopping or get a drink at one of the many tavernas set up near the port. The people-watching is fabulous.
