So, having just sailed on the Summit, I can confirm that shorts are being worn in the MDR and Tuscan Grille. There weren't a lot of people doing so, but there were definitely shorts ion all ages ncluding a woman wearing spandex type shorts in the MDR. And, no, this was not just on the first and last nights. And, you know what else, no one cared at all. Everyone was too busy eating and minding their own business. I only took notice and am reporting here because of my post asking and all of the other posts about it.
