Hello Yes I did it last year and I'm doing it again this year. I booked the Disney transportation to and from the airport ($75pp, but in my opinion worth it for the hassle free experience) and I make sure my flight arrives before their latest recommended time (Which I think is 1pm?). When we did it last year, our flight arrived around 12:45pm and we were on the ship by about 2/2:30. I think we have to be on the ship by 4 so this gave us 2 hours of wiggle room for flight delays and what not. For a single flight (no connections) I think that's a good margin.
