I am an airline pilot and I get nervous every time I go flying! Just kidding
Remember, the pilots flying you are very good at what they do.
Like I used to say to my passengers when they told me they were nervous,
"Do you know whose safety I value the most on the airplane today?"
The answer is:
"ME!"
And because of that, all passengers are covered by the same umbrella of safety that use for myself.
I would be more worried about getting an ADR than I would about the flight to and from MCO.
BTW, when I flew passengers, my most favorite flights were into MCO. Everyone was always so happy to be going to WDW. One of my least favorite flights were out of MCO. Everyone was usually grumpy from burning the candle at both ends. I do miss walking down the jet bridge during boarding and telling everyone I had a fastpass so I could get to the cockpit quicker.
