Hi, Civitanova!! Welcome to cruise chat!! We will endeavor to help you with all of your questions. First of all, let me explain a little about the web site. The most helpful tip for new people is to use the "Find" tab highlighted in blue at the top of the thread. Once you hit that, enter whatever port (or anything else you may be interested in) you want in the "Keyword Search" box. Then, simply hit "Go" and it will perform a search through the history of the website to find threads that best match your keyword(s). It's a very helpful tool and will give you the most information in the quickest amount of time. That being said, I am very passionate about Santorini. It is my favorite port in the world. It is beautiful, historic, and full of culture. I never take land tours there. I always rent a car (usually about 25euros for a full day) and set out on my own. The roads are easy to navigate and it's really the only way to see the whole island. You can drive from the northern tip to the southern tip in less than an hour. There is so much to see that you will want to go back and catch the things that you missed. Let us know if we can help you further. Once again, welcome, and I hope that you are getting excited about your upcoming cruise adventure!!
P.S. If you need information about Venice, let me know. I like to go there and can potentially help you get around town and to the cruise port.
