During our stay at Kos we also made a trip to Rhodos. The plan was to fly domestic roundtrip over the day and be back at Kos in the evening. Unfortunately our plane broke down on Karpathos and the trip back was cancelled. So we had to stay the night in a cheap hotel in Rhodos town and return the next day by boat.
We didn't know that when we toured the town in the day and among other places visited the castle. Rhodos in July, which this was, was full of Scandinavians. In the evening we had the impression that nobody but we were sober. Terrible place. But the castle was nice.
