I haven't read through this entire thread, but I do think this is an awful idea. I'm a total dog person and our Rottie, Boo, is definitely a huge part of our family, but never ever would I think it'd be a good idea to take her on vacation with us. She's a complete sweetheart and everyone that meets her, loves her, but I'd feel like a horrible person leaving her alone in a hotel room for hours on end. What kind of day is that for a dog? When I'm at work, she's home alone, but she has run of the whole house (minus the bathrooms).
From the perspective of a person in the medical field, it's also a horrible idea when you take people with allergies into account. No deep clean can erase every speck of hair and dander. They'd need to replace the carpet and furnishings after every stay to ensure it won't cause an allergic reaction if the next guest checking in has an allergy. And, we all know Disney won't be replacing a thing. What about accidents? Old urine smells horrendous. Wet dog smell if you're caught in the rain? No, thanks. I've read that as the dogs are allowed on DME if a person has an allergy they'll need to wait for another bus. What if the next bus also has a dog? It hardly seems fair.
A couple of years ago my mom and I were in line for RnRC when another VIP tour guide came walking down the ramp with a small pink ruffled carriage. Our guide joked, "What? On doll duty?" and the other guide goes, "No, dog duty, apparently." Sure enough, there was a little chihuahua in the carriage dressed in a pink princess dress and pink nail polish. The owner claimed the dog as an emotional support animal. My dog provides me emotional support too. She's a fantastic listener and a great cuddly bear. But, if I were to throw her into a princess dress and prance her around the parks, I do believe people would have a lot to say as she's 110 lbs and can't be carried in the crook of my arm like a newborn. Anyway, point is, I think this test is going to open the doors for people to claim emotional support in order to bring their little fluffballs into parks proper, and not just on hotel grounds. I think we'll be seeing an uptick of four-legged friends in the parks, and I'm just not okay with that.
