After being to Disney World over 50 times from the year it opened until right before Covid not many non locals can have possibly visited more than me.
I never understood anyone that used the Magical Buses or even the onsite buses. As a kid my parents has us use the buses and yes for young kids running around by ourselves(back than even at age 8 we could do as we pleased unsupervised and rode the buses without supervision all day long !). The buses were great for that, but once I could drive forget it.
As soon as I was grown it was a rental car, once I had my own family that continued. Some trips we would have other families go with us or meet us there and 100% of the time me having a rental car, even with the wife saying we didn't need one because heck they didn't get one, we had a much better trip. We were always waiting for the families that had to jump on the bus. They were tired, hot , sweaty, we were ice cold in our car and on time everywhere we went. Having my own car at Disney has always the way to go for me. Season passes, a rental car and fast passes(when they started) proved so successful for our trips no matter what time of year(though we have our favorite times) all our trips were and are based on having a car right from the airport, how could it not be?
At dinner we would hear people complain about lines, the buses etc as my wife and I and even my kids jaws dropped as we were saying only minutes before how easy it was getting from place to place, how the rides had fast lines and how dead the parks seemed. I had one guy say how horrible it was, I thought why even come here then? I could see his stress on his kids face, I am sure many have seen this, the dad not looking to be having fun etc. My kids and I were smiling away. After talking to the guy about having a rental and me having reservations months in advance and planing each day I was dumbfound to find this person came to Disney with 4 kids and no plan. He relied on all Disney transportation in the blistering heat.
Disney made it seem so easy to him and he relied on the Disney information he received. The impression I had was Disney almost pushed him to believe he could rely on the in house transportation for everything from airport to getting to parks and have a great trip, like it's some small resort (yeah 42 sq miles). How could the Magical bus survive when people had those experiences?
That could not have gone well for Disney and if it happened to this guy it happen to thousands. We were running around in an ice cold car with reservations, fast passes and each day planned, as I do for every trip down, he had the opposite experience and it all started at the airport for him having no car of his own. Heck, with cell phones it is so much simpler than back in the 80 and 90', even the 2000's to plan. The bus system and even Magical express should never have been viewed as anything more than a complement to a rental car, only my opinion of course.
For me all trips are based on having a mini van rental and I couldn't dream of any other way for a trip to WDW personally. As far as a business decision and peoples comments on Disney not being able to fill rooms? I have a different views. I see nothing but blue skies and butter flies for Disney. I believe they will be more busy than ever. There is no downside for me, if they get more busy great, they expand , more attractions and Disney just keeps getting better. If they can't fill rooms(again I just do not see this) less people and my trips are even better. I may be biased, we purchased a retirement home 6 minutes from the door and Love WDW.
