Absolutely! Apply the industry standards to their policy. As many have pointed out, numerous 4 and 5 star hotels worldwide are pet friendly. Universal resorts are too. However, these policies have clear weight guidelines (25 or 50 pound max) and are also clear that dogs are never to be left unaccompanied in the rooms. Taking steps to make the policy clear, outline the accountabilities of the dog owners should their dogs inconvenience other guests and clarify how situations will be handled when guests are inconvenienced.
But I'm guessing you didn't expect me to have reasonable or rational points of what I'd like Disney to fix/change. Because I am, according to you, a whiny adult that doesn't approve of this policy.
