Our neighbours got the water taxi into Fethiye yesterday. They did some shopping and they had a meal at the Mozaik Bahce and then headed back to the water taxi, just see one leaving. They waited for the next one. When it arrive at 7.30pm. They were told by the guy "Finished" no more taxi that night.
So, just a warning that if you are depending on the water taxi, have a back-up in mind.
