I just requested a "Help" chat on the WDW official website, today. The chat person advised that the only Little Mermaid rooms that will allow dogs are Bldg 7, floor 1. However, a guest reported on another thread that they saw dogs coming out of 2 separate rooms in Bldg 9, floor 1.I emailed them last week, got a phone call from guest services. Regarding AOA- pets will be allowed in Little Mermaid and the Cars suites. No specific rooms or floors there. Walking areas are behind these locations and no pets in the common area. I also got the information about the waiver guests with pets sign and that any guest who wants to see that waiver may request at the desk to see it. The general information I got matches what others have posted here. Disney seems to be very consistent in what they are telling guests.
It is frustrating for me because I want to request a specific room in advance. I definitely do NOT want a dog room. And there are so many conflicting reports and obserations about which rooms are guaranteed dog-free.
