Don't know who this guy is... but he is really committed to his opinion. It is just that... his opinion.
Many people have other reasons (just as valid) for NOT using DME. (e.g. They need a rental car.)
From what I compared with the two families I know who used DME and my own recent trip (1st week September). Ours was a much better experience. Less time consuming. Less frustrating. And it didn't "ruin our 1st day there" as it did for the two families I know. (The 2 families waited about 7 and 14 hours for their luggage to magically arrive, which they did not anticipate... they had that "herded like cattle" feeling... and they both complained about driving around picking up other passengers... they just wanted to get there!)
We rented a car (L&M at the airport $60/week), collected our own bags, installed our car seat in the car, and got to Wilderness Lodge (in about 1 hour). This afforded us the luxury of using a car instead of Disney transportation when needed (e.g. to all resorts, to AK, to EPCOT, to DD)... WL buses stop at Fort Wilderness which I hated, so we took our car to the parks and parked in
AAA diamond parking. This cut our travel time to <15 min to WDW properties... as opposed to 45min to 1 1/2 hours, when we did try Disney transportation.
For the return trip day, we checked our luggage at Wilderness Lodge and got our boarding passes... you DO NOT need DME to do this!!! We spent the day at AKL and DD, and then drove to the airport. Leaving DD to airport (including gas fillup, rental car return) took < 1 hour. All we had to do then is walk to the gate.
That is another option to DME and just as valid. I doubt the other transport companies are going out of business any time soon. Unless WDW can improve it's transportation system (something more like a subway system) and have access to a grocery store and hospital/medical center... we will never be able to use just Disney transportation.
