I'm about to travel with family to Korea for a week. My home has a Apple TV 4K 64GB and something just hit me: the hotel room we booked has a 40 in. TV so why don't we load up the Apple TV (or iPhone / iPads) with some Bluray movies I ripped and watch it on the big screen? Can the Apple TV store any movie locally? If not, can I stream movies from iPhone to the TV without wifi. The hotel has wifi but I'd rather prepare for a plan B where the wifi is too finicky.
