On our 4-day WonderMoon last year, on the day at sea, there was a big rainstorm. However, Captain Henry just kept skirting around the edge of the storm all afternoon. Then, when the majority of people cleared off the decks to get ready for early dinner/show time, they swung a hard left and drove through it. By the time the late shows were done, we were through the storm and we could go out and enjoy the open decks.
Very cool, I think.
