Um, I truly respect all of the CMs who, given nearly impossible guest expectations, still manage to keep the pixie dust flowing - and a smile on their faces. However, if you tried to compile "Disney policy" based solely on what CMs, Managers and Supervisors tell guests in individual encounters, you'd quite simply go mad. Some of the most contentious issues discussed here (pool hopping, room capacity, mug refilling, etc.) are issues solely because, over the years, well-meaning guests are told many different answers to the same question. Add to that the concept that in some cases, while Disney may have a policy, it enforces it selectively - or not at all.
And an experience of mine - way back in the mid-90's - sums this all up: [Anecdote warning: no factual support]. My wife, son and I were checking into the CR (Tower, facing MK woo hoo) and I asked the CM a question about watercraft rentals - what age you had to be (a big issue for DS). She wasn't certain, and asked two manager/supervisors who happened to be chatting behind her. While I was only 3 or 4 feet away, I witnessed them arguing about the issue - one thought it was one age, the other vehemently disagreed.
My personal opinion (yep, I know you've all been patiently waiting) is that Disney needs to publish (I think the legal term is "give notice") of the rules, and then enforce them in a consistant way. Otherwise, the guests, and CMs, and managers, and supervisors have no idea what's expected, what's allowed, and what's prohibited.
