Long time reader, first time joining and poster.
Having just returned from Art of Animation two days ago, I can tell you they do not have
Disney+ on the television. I was hoping for this myself and thought what a terrific way to promote it during your "trial period" while staying on resort. I do know they had swag giveaways in Disney Springs, but I missed these.
On Channel 30, they play a roller of Mickey cartoons. Every morning while I sipped my coffee, my 12 and 9 yos, would watch these cartoons. Eventually they began to see the same ones over and over again. I installed Disney+ on my Samsung S8 and let them watch many, many more, albeit on the small screen of the phone.
I then paid attention to the TV in the room and learned it is a Samsung. I was able to Samsung Smart View my phone's screen to the television (using the TV remote's source selection button). When Disney+ would play it would fill the entire screen and for the remaining 4 days, my kids got a eyeful of Disney+.
