Orlando International - MCO They really should rename this airport "Theme Park" or "Disney's Airport". If you are arriving and headed to the Magical Express, it is super easy. (as of 2022 this will end).
If you are flying Internationally, collect your baggage at the carousel
if you are flying domestically and you put the yellow baggage tags that were mailed to you on, onto your luggage, Disney has already collected it for you. If you did not do this, you'll have to collect your luggage.
Then head all the way downstairs. You'll be in the car rental area, ignore them and turn left, walk right by them (because they'll be on your right side - see what I did there...), all the way to the end of the hallway and *BAM* you've found the Magical Express. Make sure to have your reservation handy as they will check it and then tell you which line to join. If the line to get checked is long, do not jump into the bathroom right beside you as the line will move fast! (Yes, I have made this mistake...).
This free Magical Express (gossip is that it will stop running once the Brightline terminal is built as this connects the airport directly to DisneyWorld via train) coach runs quite quickly. Seats are plush and there is a video about the Disney park that runs on a loop for the roughly 20 - 45 min (depending on where your hotel is located & how many stops along the way) drive. Feel free to nap. It is just highway until you get to your hotel.
The nice thing about the bus is not only do you not need to drive or find locations but you also don't have to pay for parking. As of 2020, none of the Disney resorts allow for free parking for their resort guests so you'll have to pay a nightly rate that is similar to the daily rate park going guests pay.
When you are taking the Magical Express back to MCO, the coach will normally pick you up 3 hours prior to your flight due to the stops they need to make at the other hotels along the way plus any accidents that may be on the highway. If you are flying domestically then you can check in for your flight at the kiosks near the hotel's check in desk. If cannot get a late check out but are going to head into the park before the coach picks you up, the hotel will store your bags until you return.
Due to the Brightline Rail extension from Orlando Airport directly to Disneyworld, this service will end 1-Jan-2022.
