Considering your interests (great food, hiking, beaches, nightlife unimportant) then Naxos should definitely be your other island. (And Naxos has many daily ferry connections with both Santorini and Athens.) Also, Athens needs at least one full day to explore so you should drop any thoughts about Delphi or Nafplio. Also, I would look into flights from Athens to Santorini on your night of arrival. If you could get to Santorini that night (and move your day in Athens to the end of your trip) you’d almost gain an entire day and could spend two nights on Naxos.
We are two guys in our early 30s, we have 12 days for the Greek Islands. We like to swim, ride bikes, or drive on the islands to explore villages, culture, local life, love to eat local food, rest and have beers on beach, stroll and walk around in evening, etc. We will go to Santorini for 3 nights and select Fira according your suggestions, we are confused for next island between Crete and Naxos. Crete is huge but if we choose Naxos as it’s easy to reach from Santorini than does 8-9 days will be boredom in Naxos? Please suggest what’s best and on which place we should look for accommodation in either island you suggest..
Between Nydri and the next main tourism centre is the little port and beach of Mikros Gialos (small bay) that is a great little base for individual travellers for a day or three. The port village of Vasiliki on the southern underbelly of Lefkada is a haven for windsurfers: see this page or this one for more information. The little village is very pretty and is a good base for general holiday-making (as are the two other places). From Vasiliki there is a regular local ferry that runs to Fiskardo on Kefallonia (via Ithaca/Ithaki).
We are wanting to hit 3 islands and have narrowed it down to Corfu, Crete, and Santorini. I was feeling pretty good about this but I haven’t seen a lot of hype for Corfu. I was thinking it would be more unique as compared to the other 2 with its proximity to Italy and Turkey and Albania. Am I missing something, do you have any insight you could provide, please?
There are many picturesque villages to explore, and the beaches are always far from crowded. If you like walking, the lush vegetation and cliffs are ideal, while if you like to do some underwater exploration, there are many scuba diving and fishing opportunities, too. Additionally, Dugi Otok is home to one of Croatia’s best sandy beaches, Sakarun, which some compare to the beaches of the Caribbean, making it a great family spot.
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.
