About us: I'm in my early 60s and my GF is in her late 50s. I've cruised over 20 times, mostly on Celebrity & MSC.
Full Thread/Blog: I did a day-by-day write-up called "We board Infinity in about an hour. Let me know if you have any questions". It goes into considerably more detail.
Overview: This was a 7 day cruise out of Ravenna, which is about 3 hours from Venice. It stopped in Dubrovnik, Santorini, Rhodes, Kusadasi, Nafpilo, and ended up in Athens.
Cabin with a huge window. Was formerly part of the conference center. Cold showers in the morning, at times, but otherwise pretty good. See my video review on YouTube (I think there are 2 reviews for the same cabin, but mine is more recent 09/23).
