Unfortunately, so are some of the dogs.
Not sure how it is in other countries, but nowadays in the United States, it's rare for as many as 85% of the people to agree on any issue, yet currently this poll indicates that about 85% of us prefer no dogs in WDW resort rooms. This is an overwhelming majority, and I find it odd and sad that Disney would disregard our strong preferences and concerns on this matter. Many of their communications display a lack of understanding of the extent to which being around dogs can trigger medical and/or anxiety problems for much of the human population. For example, the form letter they sent to many of us on this forum, mentioned that "dogs are beloved members of the family". While this is true for many people, it is also true for lots of other people that dogs trigger allergies, phobias, etc. to the point where encountering a lot of dogs or their dander on vacation can be worse than skipping the whole vacation and staying home.
This lack of care for guests concerns me even more than the policy itself. Guests spending thousands of dollars on their vacations may not be comfortable to encounter dogs, dog waste, pet dander, etc. at their resort. It does appear that dogs will be on the resort walking paths, maybe in the lobby for check-in, and will probably end up all over the property, just as the "dog relief" areas are all around the maps. During the hurricane, dogs were officially not allowed in the food courts, yet there were reports on these boards that people saw dogs at the food court and nothing was done about it.
I can only imagine how much effort it would take to restore the resort rooms to pre-dog condition if Disney ever decides to end this policy. To remove all the pet dander, pet smells, pet stains, scratches on the floors and furniture, etc. would require a complete refurb of the rooms -- and since YC was recently refurbed, it seems unlikely this would be done again soon. So in some sense this decision seems irreversible. For the most part from my experiences at moderate resorts it looked to me like mousekeeping was not doing a thorough job even cleaning up after previous human occupants. Some of the times I requested an allergy cleaning, the room I received did not appear to have been cleaned even to what I would consider minimum standards, let alone allergy standards. Adding dogs into this only creates more issues for those with allergies.
This thread has gotten so long that I'd like to repeat for anyone who missed it: if your trip is coming up soon and you are feeling stressed and trapped because the resort you booked at is now dog-friendly, and all the other on-property resorts are sold out (as happened to me), then maybe you still have the option to cancel and switch to an offsite hotel. I feel so much better having done this. Sure it is disappointing not to be able to stay on property, but for those whose idea of a fun and relaxing vacation does not include the risk of encountering dogs, dander, dog waste, etc. at your resort, why subject yourself to this stress that you didn't sign up for? There are lots of offsite, no-dogs hotels with available rooms even when the on-property resorts are sold out. You might even find a new favorite hotel.
