Which of these great locations would you recommend for a family with teenagers who like to dive and surf? We have been to Hawaii, Costa Rica and Tahiti. We are looking for a safe, yet different, cultural experience with exotic plants, fish and animals. We would prefer to stay in one villa, as opposed to multiple rooms in a hotel. We don’t mind if it is far away from Southern California. I realize this may be painful financially.
The other groups are best tackled individually. For example, the Ionians have no ferry connections to the rest of the Greek islands; the same story with the Sporades and the Argo-Saronics. The NE Aegean islands do have a link to the Dodecanese and the Cyclades but are probably best left for another trip once you have got the feel of the rhythm of the Greek islands.
Krk is a large island and it has many towns and villages to explore, as well as fun campgrounds and resorts to stay at. Connected to the Croatian mainland by a bridge, this is a very accessible island. Krk has varying landscapes, with an arid feel to the north, a lush green side to the south, full of bays and beaches, and the interior is hilly and rocky. If you want to enjoy wildlife then head into the woods on one of the many walking trails and see what you can spot!
As you head south, high-rise resorts give way to stretches of golden sand, such as Glystra, Tsambika, and Fourni. Inland, you'll find alpine forests (Mount Attavyros), hilltop castles (Monolithos), faded frescoes (Agios Nikolaos Foundoukli) and ancient ruins (Kamiros). Marooned on the southern tip, Prasonisi is a powdery peninsula where the Aegean meets the Mediterranean. One side is calm, the other choppy - a metaphor for this island of two halves.
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.
