First of all, Greece, just before the busy tourist season... end of May, a great time to go. The air is warm but the oceans aren't...
We did Athens, Mykonos and Santorini in 10 days... we left from YYZ
Little known fact about some of the hotels...Mykonos and Santorini...don't have drinkable tap water...its all bottled...
Which means, that in 2 hotels, especially Giannoulaki Delian Collection property in Mykonos, a simple cup of coffee in the morning is very , very difficult to find... theres no coffee machines in the rooms
You might say that coffee is not a big deal, however, with the time change, its easy to wake up early and wish you had the luxury of such a cup of Java, while you take in the beauty of the countries landscapes..
