Are there any pet friendly pull thru sites remaining?
They don't add pet loops. But, they will put pets in non pet loops if need be. You may also get upgraded to a premium pet loop, 400 and 500 are right across from 300. It's all good.
The Disney CM we spoke to when we made our reservations told us that the 1600 thru 1900 absolutely did not have cable. Even after we told them that we had read online that it had been installed.
