They could require everyone be out of the room between the hours of X:00 and Y:00.
Given WDW marketing, I genuinely think that even if every single DIS member stopped going, it would not affect Disney revenue.
No idea, but I would expect the majority of trip planners use some unofficial source, guide, forum, etc. Not all, of course. I'd be surprised if Room Check information weren't provided by at least the best sites.
Yes, I understand not every room has the door hanger - but the/any company prints and provides the information, and really can't be responsible whether people opt to read it.
With th numerous threads on this board alone, I'd be stunned if anyone weren't aware of this readily available tool. However, there has been not. one. single. report. of any CM using this tool on any guest room, ever.
Just general information:
DisneyLand = Happiest Place on Earth. Walt Disney World = Most Magical Place on Earth.
Now you've done it!
Genuinely don't think anyone is scoping out any guest underwear. If they were, though, underwear on a shelf is - underwear on a shelf.
Request a woman CM. Step out of the room. Stay somewhere that doesn't do random room checks (but not an Omni property because, well, they do.)
