It’s best to visit Greek islands within the same group. For example, I wouldn’t recommend visiting Corfu and Santorini on the same trip as they’re on opposite sides of the country. Instead, visit islands in the same island group: the Cyclades, the Sporades, the Dodecanese, the Ionian, the Saronic, and the Northeastern Aegean. For one, they’re close to each other. And two, they have frequent ferry connections with each other. For first time visitors to Greece, the Cyclades make the most natural and convenient introduction.
If a particular city has two or more airports, market forces will tend to attract the less profitable routes, or those on which competition is weakest, to the less congested airport, where slots are likely to be more available and therefore cheaper. For example, Reagan National Airport attracts profitable routes due partly to its congestion, leaving less-profitable routes to Baltimore-Washington International Airport and Dulles International Airport.
We are having trouble deciding on another island to go to besides Santorini (we both want to go there). I was hoping you might be able to make a suggestion. We are not really into late night partying/night life. We LOVE good food..quite possibly the most important item on our list. We also like to hike, my husband is very into history, we love beer/wine, we could definitely be into in a less populated/touristy type spot. Gorgeous beaches and great views are also a plus.
