Pickleball on Celebrity Eclipse is played on the SportCourt that is at the front of the ship. There is no space between the baseline and the net surrounding the court. The wind is terrible and makes playing almost unplayable while under way. There were quite a few that showed up on the first day, and almost all the experienced players gave up and didn't play again. I have cruised Royal and Celebrity about half and half. On the Eclipse, the court does not work well unless in port and it's not windy.
