Here's a nice travel blog that we discovered, from a nice couple calling themselves "PJTravellers". They were in Rhodes in May 2016 and this is what they wrote about the trip:
"What a perfect day to visit Rhodes: nice wind but not too hot, clear skies and interesting sites. We had some excitement arriving at the dock as the wind was against us and we had to very carefully ease into the space. We had some help from a little tug, Herokles 3, which managed to push right up against the portholes of our cabin. Peggy heard a noise and looked out the porthole to see a gentleman with a cigarette about four feet away! Once settled we enjoyed a fine breakfast. Then we left the ship early – around 8:15 – and walked into the old city … which was deserted as nothing opens before 10:00. Except the Palace of the Grand Masters. This was where the Templar Knights settled and built fortifications in the 15th century after leaving the holy land. When the Ottomans took over from the Italians the place declined and it was Mussolini who rebuilt it in the 1930s to honor Italian heritage and Emperor Victor Emanuel. The Italians did a great job of repairs even if they were hard on the people of Rhodes.
After walking through a bit of history we walked down the street of the knights as represented by the French, Spanish, and English. We saw a monument to a knight who died in the hospital/hostel down the street and had been sent to the holy land by King Ferdinand in 1493. The room where the monument was placed had numerous little cubby holes off the main hall where the very sick could be separated from the rest of the visitors.
We wandered back down into the old town, now incredibly alive with merchants of every kind, selling whatever tourists wanted and didn’t need. We stopped at one shop to have our feet scoured by little fish. What a sensation to have dozens of them taking the dead skin off and tickling you. Can’t say that we noticed a difference but it certainly is unique. The owner of the shop shared with us his sadness about being part of the European Union and how it diminished the number of Americans who came because the drachma was so cheap against the dollar.
