My flight was canceled the day before the cruise in February, 2021. We were able to reschedule for a new cruise two that departed two days later without penalties because Disney had already altered our itinerary due to Covid-19 stuff.
It was so weird. We had a sudden ice storm that basically shut down the entire region. I couldn't find a flight down to Orlando within 250 miles. Our best bet was to take Amtrak half way there and then catch a flight the next morning and arrive somewhat later than planned, but we were just a bit too late to get the train. Oh, well. Weather is chaos.
