Groups such as the International Civil Aviation Organization establish worldwide standards for safety and other vital concerns. Most international air traffic is regulated by bilateral agreements between countries, which designate specific carriers to operate on specific routes. The model of such an agreement was the Bermuda Agreement between the US and UK following World War II, which designated airports to be used for transatlantic flights and gave each government the authority to nominate carriers to operate routes.
Crete, Santorini, and Naxos look quite doable within the 12-day block, but Crete’s beaches are scattered throughout a very LARGE island, Santorini really only has Kamari and Perissá (and some southern coast bays) and Naxos does have nice places to swim. If you choose only to visit those three islands in your relatively short time, you will do well.
Yachts moor in the deep, sheltered harbour of Vathy, or Kioni, a miniature port where you’ll find Spavento, the perfect pier-side café-bar. Go any time of day or night for ice-cream sundaes, excellent cocktails, and a soundtrack to make your heart sing. Ideal for low-key family holidays or retreats, rugged little Ithaca is somewhere you can still disappear.
