Thank you for your reports, Bob.
During my visit in May / June this year in the Sfakia area, I also experienced the very friendly wellcome almost everywhere. People had time to sit together with the tourists, chat a lot and were relatively relaxed regarding the difficult situation. I would say this was my best time in Sfakia, comparing the last 5-6 years.
The 'shower ripp-off' on Gavdos I would see a little different. Last year there were more than 6000 visitors on the island in August, most of them camping. This is more than 100x the normal population. I can understand, that the showers can't be for free for so many people (although 1 EUR per minute is probably too much).
The tavernas make good business, but the water, waste disposal and the infrastructure the island provides also add up. And the water supply on Gavdos still is not without problems.
