Bermuda is recognized as one of the most elegant of the Caribbean islands, and also on the formal side. It has a strong British influence, and you can still find many places that serve traditional afternoon tea. Cricket matches are also easy to find. Bermuda is also a great destination for golfers, as the island has many world class courses. This island is extremely convenient to reach from the Eastern U.S. Flights from New York to Bermuda are only two hours.
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.
Antigua is a small island that is often grouped with its nearby neighbor Barbuda. A popular gambling destination, Antigua has a good selection of casinos. It also has plenty of other exciting nightlife, including great restaurants, cafes and discos. The beaches are also spectacular, and you can find literally hundreds of them, with both white and pink sand.
They’re all great choices. Athens (1 to 2 full days) is great for historical sightseeing. Mykonos for beaches and nightlife (2 to 4 days). Crete for historical sightseeing, greek culture and towns, some beaches but spread out (4 to 7 days). Santorini has great sightseeing, tours, and some history (4 to 7 days). If visiting outside of June to September then drop Mykonos and do the other 3 for sure.
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.
