The Dream did not this year. We had to switch the CC day/sea day because of Sandy, though. So whereas Halloween should have fallen on a sea day, it was the CC day instead. That may have put a damper on their plans. There were CMs wandering around the Halloween party (up on the pool deck) dumping handfuls of candy into kids' bags, but no trick-or-treating. In fact, just yesterday my 8yo was lamenting the fact that her candy bag wasn't "filled to overflowing" (her words!) as usual when we are home. It's a long story involving it being a surprise cruise, but we will never do another Halloween cruise again. It just wasn't special enough for my kids. As in, they would rather have had the one big Halloween day at home than 4 on the ship. I think that's totally crazy, but Halloween is important to an 8yo and a 5yo I guess. Gotta have priorities!
