best streaming (TiVo or other) for hotel TVs?

I hate watching a small screen while sitting in a room with a big screen. I'm looking into options for streaming (TiVo or Netflix/HBOGo/AmazonPrime) to hotel TVs, assuming available HDMI connections.

• ipad<->HDMI adapter: Does the TiVo iOS app work with one? I've seen some posts that claim that not all apps let you use that. What about Netflix, etc. apps?


• Chromecast: I have one, but would need a travel router to work around the typical hotel wifi login screen.


• Roku 3: Too big for travel or not? The new Roku stick availability is too far out for me.

Opinions? Other ideas?



Thanks,
