That's fine. I truly don't expect to change your mind, just expressing my own view points and concerns.
Since you singled out the "irritating" part of my post, ignoring the worse "may cause harm, like allergies or bites" part, I'd like to expand more on the barking issue. Personally, I don't really consider incessant barking a "what if" situation. I think it's a foregone conclusion, but YMMV.
Several people have expressed negative experiences at pet-friendly hotels with barking, (among many other things, but I'll stick to barking right now). According to a hotel manager at a pet-friendly resort in another thread, barking is the number one complaint. And when they call pet owners to tell them their dog's barking is annoying people, the response is usually "No, my Fido doesn't bark!"
But hey, it's just one data point. Maybe Disney dogs won't bark.
