I went to Disneyland/DCA in October 2016, and the California Screamin‘ coaster stopped near the top of the lift hill.
warm day, bright sun, they ended up having to evacuate the train 2 people at a time
I thought about it a little more, and I wouldn’t be surprised if the boarding groups stay until such time as they last the whole day without filling up
Tough choice, I could go both ways.
I’d say, see how you feel after the cruise. If you’re up for it I’d say hit a park on the first day. Maybe EPCOT, just spend time around World Showcase.
Then your last day I’d say spend at Disney Springs, or resort hop and explore
