Distance Learning: 2 Years. Many schools offer online master's programs, allowing students to work at their own pace without having to travel to campus. Other schools may provide a mixture of distance learning with classroom lab work and/or on-site classes.
Fantasy Travel actually has a 12 day itinerary that begins in Athens, then you go to Mykonos for 3 days and from there you take a cruise that goes to the islands and Turkey and ends in Santorini, where you get off and stay for 3 days before going back to Athens.
The weather in Santorini on May is always good. The average temperature is about 19 degrees. Late in the afternoon and evening it's cold but not too much. Dependants on you and in what weather you are used to (like the country you are coming from). October most of times is hotter than May.
