Your timing is great because as you emailed me, I am actually in a Marriott hotel where they have the latest generation of LG hotel TV that includes the Netflix app and a Netflix button on the remote both. Most seem to make an external HDMI plug easier to access and choose, and one of the latest places I stayed had a built-in Chromecast for all of its TV sets.
I’m certainly not spending as much time in hotels as I was 18 months ago, but it is great to see that hotel television sets are starting to be redesigned to include guest-friendly media features.
