Also, if there are any other suggestions you have in general for Athens and Santorini I would love to hear them. I would like to be able to leave Athens early morning on Day 3 so that we can have almost a full day on our first island. We would like to see as much as we can without feeling like we are running around from island to island the whole time.
To island-hop some of the most beautiful havens in the world, book a trip to Asia, which lays claim to six of this year’s top 15 destinations. But if you only have a week, you’ll hardly suffer. Each of the islands on this list is worth a visit on its own, from the perennial World’s Best list-makers Maui and the Galápagos to Portugal’s rising star, the Azores, with its friendly locals and awe-inspiring landscapes.
Be cautious with Santorini and kids. Some hotels don’t do kids (check carefully) and not all hotels are suitable for kids along the caldera lip. Many steps, confined spaces and other guests who don’t actually want to hear kids … Here’s an idea – look for a child-friendly hotel (perhaps on the beach at Perissá) and base yourself where the kids will like it and then take them to the caldera scene. There are a couple of child-friendly hotels on the Caldera, but they get booked very early in the year.
Since airline reservation requests are often made by city-pair (such as "show me flights from Chicago to Düsseldorf"), an airline that can codeshare with another airline for a variety of routes might be able to be listed as indeed offering a Chicago–Düsseldorf flight. The passenger is advised however, that airline no. 1 operates the flight from say Chicago to Amsterdam, and airline no. 2 operates the continuing flight (on a different airplane, sometimes from another terminal) to Düsseldorf. Thus the primary rationale for code sharing is to expand one's service offerings in city-pair terms to increase sales.
