On the Celebration, it was set up as a tournament, just one night. It was late- on the basketball court, after basketball was done for the day (maybe 10 pm?). There were some cheap paddles, but most people brought their own. There were temporary court markers for the kitchen/court lines, and the person running things was very serious about calling kitchen violations.
I think 1 person showed up who hadn't played before. I think it was 18+. It was well organized, but didn't last that long. I had fun, was nice to play on a ship and meet some new people. I'd toss my paddle in my bag just in case I get the chance to play again.
