I was idly fantasising about a summer trip to Orlando this afternoon. No real seriousness to it. Just a bit of fun.
Anyhoo, the rules are that you have to wear a mask at the departure airport, and on the plane, and at the arrival airport, and on DME (presumably, if it’s still a thing) and in the public areas of the hotel (yes?)
So for a UK guest, that’s about 15 straight hours of mask wearing with no relief. Virgin Atlantic’s website even notes that masks last about four hours at most, so you should bring a supply with you on the plane to be sure you can remain covered at all times.
