We've done a few. Usually, they are just organized on the cruise meet cruise thread here on Disboards. On our last cruise, nobody on the thread was interested, so we just did one ourselves - we put goodies in our fish extender once a day while the kids were out at the Oceaneer Lab.
Hi fellow New Year's 2020 cruisers. Just 45 + more days to go now. I invite all other fellow cruisers up to deck 11 on New Year's Eve (also my birthday) for a glass of champagne and fire works on Mickey. I will be the one with a large Happy Birthday button on for the New Year's countdown party. Hope to see many other fellow party people on the pool deck!!!!
