This is a low volume product. Have you considered Disney may not even let people book this experience without going through a live agent? Where all this managing of expectations can be controlled?
The last thing Disney wants is whales showing up after dropping 5k and complaining they want their money back. Disney will be motivated to ensure booking guests know this isn't just their hotel for their WDW trip. The fact people keep stumbling in here repeating this just shows their personal lack of effort.
You mean like you can find people on these same sites that don't even know the basics like operating hours, or what FP is, or can't figure out when an attraction is down for rehab, or get upset that a bus doesn't show up on demand? Does Disney have problems with people publishing bad info on these topics and Disney is at fault for not correcting them there either?? No right?? So is it a Disney marketing problem, or is it just an indicator the person isn't doing this part to be educated?
In short.. you can't fix stupid. There are always going to be people too lazy or too selfish to get informed - so you're always going to have examples of people stumbling in to ask the obvious. It doesn't really tell you anything besides the Human race generally sucks.
