Santorini- if you are going to visit the picture perfect Oia (a must!), best tip is after you get off the tender there is a company right there (aegeantraveller.gr) that sells boat tickets 15€ and take you to Oia which also include bus transportation back to Fira. (This way you don't have to wait for the small cable to go up to Fira and then have to take a taxi (25-30€ one-way) or bus to Oia). ...
We took a boat to Oia. All the photos of Santorini you see -- White houses against the Blue Mediterranean Sea! So pretty!! Narrow streets are Very Crowded with tourists. Know of 3 weddings while we were there (saw 2 while in town, and one bride and groom was on our ship). Bus to Thera (?), and took the tram down to the water front instead of dealing with the donkey poo on the stairs. ...
We enjoyed visiting Santorini, a beautiful island with classic Greek architecture. We had lunch in a little cafe looking over the Mediterranean. The donkeys detracted from the experience of walking down 600 steps to reach the port. ...
