But most of what you say here doesn't have anything to do with anything I said.
1. I didn't say what Walt would do. How many times do I have to repeat that?
2. Obviously vacation affordability is subjective.
3. I never tried to define what $$$ of vacation is affordable for others. But that's a total rabbit hole.
If you are going to invite me down that rabbit hole...
The GoLinx bus still has drop offs on WDW property. A fixed route all-day GoLinx bus pass costs $2.25. Once you are on WDW property, there are a number of completely free things to do: walk around Disney Springs, visit the hotels, walk around the boardwalk, see the fireworks from the Grand Floridian or the monorail platform, listen to music in the GF lobby, observe the animals at AKL, see an outdoor movie..There are many DIS threads on the subject of free (and low cost) things to do at WDW.
There's also still a Mc Donald's on WDW property. I haven't been there recently, but I imagine they have the same $1 menu as every other McD's in the USA.
It is entirely possible to spend a whole day on WDW property for under $5, including food and transportation.
