Speculation yes, but by no means wild. Disney already does it at other locations and almost every other hotel in the area does it. If we were speculating that Disney was planning to do something out of the ordinary I would agree. Speculating that Disney is going to follow suite with there own business practices at other places and the industry norm in the area is pretty grounded speculation. I think we have to remember that our personal desires aren't going to change anything and looking at this from an unbiased perspective doesn't mean we agree with it.
I think you really need to qualify your comments better.
Almost NO other average hotel in the area charges for parking.
If you're talking only about 5 star hotels, then state that, because there are a zillion other options. You can stay on 192 for $25 a night sometimes. That is an available option - with no parking fee, often no resort fee, and a free shuttle to the parks. It's not all about the 5-star hotels, and most Disney resorts are not 5 star hotels.
There is no shortage of places to stay in the Orlando area, to fit all budgets and experiences.
We can stay on property every time, off property every time, or a mix depending on pricing. That may or may not matter to WDW.
But - "value" is subjective and the concept of a "good value" must be met in order for people to book the trip in the first place.
Too many big companies today don't charge what is necessary or what is fair, they charge as much as they can get away with because they can, and because Wall Street expects them to (quite unrealistically in some cases) post a certain amount of gains every year.
People getting used to that and accepting it as normal and OK is dismaying.
The only valid reason for WDW to charge for parking at the resorts IMO is as a deterrent for people trying to avoid paying at the theme park lots. All hotel guests should be exempted. When you pay to get in, you are paying to get in to the entire "World" not just your hotel. Lord knows they should be making enough money off the meals and shopping without having to charge you to park there for that very valid purpose.
