So... after all that, we're looking at extending a day.
We got a deal on the room (40% off as a DVC member). Not sure if we still can for the one night, but it's possible. It's still the same property manager that was here three years ago when we were stuck in the room with Covid.
It looks like the flights may be cheaper. I can't change it on the app, though, so I have to go through Delta's CS. Have to do this first.
I likely will not have any issues with transportation to/from the airport.
Job isn't an issue.
One of the really good things is that it allows us to have a nice dinner on our last night; right now, our last night is H2O Glow.
