You're probably correct in you assumption about most of that. I was a Disney junky for a very long time. I loved everything about it. I thought about it, wrote about it, planned for it, tried to find a way to make a living just selling WDW to those that had never been there, but I never ever felt that Disney was the only thing worth seeing. Those that never went to Universal still think that it is all thrill rides, and it does have a few more than WDW, however it has and had some of the most detailed and extravagant dark rides and a lot of them.
Even in the early days I always planned time to go to Universal, SeaWorld, and all the unique central Florida attractions and also went to the Kennedy Space Ctr., Cyprus Gardens and even the Sunken Gardens on the Tampa side of the state. I feel sorry for those that never went to Uni and experienced rides like Terminator, Back to the Future, King Kong, Earthquake, Jaws and countless others (no longer there).
With the exception of one time I regrettably stayed in a Disney Resort Hotel, I always stayed offsite and either had driven my own car from Vermont or N.C. or rented one. I was never without my own transportation. I've listened to people go on and on about how much easier it was to use Disney Transportation and thought it must be a major chore to drive in from offsite. I had friends that stayed onsite and we stayed offsite. We would leave with the mob as MK closed in the evening they went to the bus and I headed to TTC and the parking lot. When we arrived at our offsite hotel we called them to see about the plans for the next day and they were still standing in line at the bus stop at MK. And when the bus did arrive it was sardine time on the bus. I did that the one time I stayed onsite and we were packed in so tight that I swear there were a couple people that I probably should have married we were so physically close.
After 48 trips over 40 years I can count on the fingers of one hand the number of sit down restaurants that I went to during that entire time. As years went on it just got to be more and more difficult and expensive to eat a main meal there but it was easy to go to a restaurant with equally good food for a lot less money offsite with no reservation required. We'd take a break, leave the park, have a relaxing meal and then head back for the evening.
As much as I loved Disney, I never fully joined the cult. There was so much more to see and Disney was only on part of enjoyment. Just as a ending thought, there are only two themed locations that I would ever spend my money on is Disney or Universal. Both are high quality places with high quality attractions, however, WDW has placed so many obstacles in the way of my style of spontaneous travel as well as the cost that I have no further plans to go ever again.
Funny thing. I must be a freak of nature or something because I never set foot on the Magical bus in the 40 years I have been going regularly and always felt the magic. The problem for me now is I might feel the magic even now without the bus, the real problem is when I got home I would also be feeling very stressed and very broke.
