People hoping that complains will put a stop to this test, remember it took a child being eaten by an alligator to cause Disney to put a fence around an open water way.
No one at Disney saw that being an issue until somebody died, in an extremely tragic way. Mission space still operates after people have died.
The only reason Disney will change this is if it hurts them financially. The only way to do this at this time is ask to be downgraded to a cheaper hotel, and ask for a refund, which they have said is an option.
If you pay to upgrade to a more expensive dog free hotel, then Disney are winning.
