In my opinion 2 +2 =4
In my opinion people who want to maximize their time at WDW must use private transportation.
Is that better?
Lets look at the math, not opinion. A DME pickup 2.5 hours before your flight indicates you'll be happy arriving at a DME drop off at MCO 1.5 hours before your flight. Private transportation will drop you off at level 3 somewhat near your security checkpoint. Assume you're ending your vacation at DS. Taking Uber from DS directly to MCO. Leaving about 2 hours before your flight should get you to MCO 1.5 hours before your flight. You've gained 30 minues of Disney time before you account for time from DS back to your resort. Buses from DS to resorts aren't that frequent. How much time if you just miss a bus. 20 minutes? 30 minutes? How long for the bus trip back to your resort., Most guests would allow an hour., You've gained 1.5 hours of Disney time.
Now assume you're ending your day at your resort. Private transportation would give you an extra 30 minutes of resort time, probably more like 45 since you'll want to get to your bus stop a few minutes before you bus time.
Sam already made the point.
I think skipping DME altogether makes sense when a family wants to end their trip at a different resort, or park. Assume a family staying at POP wants to end their trip with a meal at Ohana. How long do you need to allow to get from POLY to POP? Monorail or boat to MK. Walk to bus. Take bus. 1.5 hours? 2 hours? The difference is leaving POLY 3+ hours before your flight vs 2 hours before your flight. The difference between having a last meal at O'hana vs POLY. How long is your trip? How often do you go to WDW?
edited to add A poster on a different board once posted A passenger who never missed a flight is a passenger who wasted too much time at airports through the years.
This opinion isn't shared by most families vacationing at Disney.
