I agree the key situation is frustrating.
In terms of the area and connecting room requests.... remember, they are just that, requests. There are no guarantees (except for medical reasons such as a non-smoking room due to ashthma). Even though your resort may have 2000 rooms, there may only be a couple of hundred open when you check in. The room assigners don't even see your reservation until 5 days before your arrival and they actually assign the rooms 3 days before arrival. I am sure they did the best they could. When you asked them to move you to connecting rooms, they were able do it, but then it was too far away? Again, I bet they were doing the best they could on such short notice, without having to inconvenience more people......
Best wishes, WDW is the best place on earth and the CM's (most of them) do whatever they can to make it a great experience for you.
