My favorite way to accomplish the OP's request is to use a Roku connected to the TV and mirror from my Android cell phone. I either stream through an app on the cell phone (Netflix, Sling, CBS All Access, etc.) or use the park WiFi to download to the cell phone (which provides the smoothest delivery). Roku is super easy to set up but does require a WiFi connection. However, when mirroring from the cell phone, it doesn't seem to consume Gigs from the WiFi. We can use slow park WiFi or a cellular based hot spot. We found the Chrome Cast impossibly hard to use, and it seemed to consume a lot of Gigs from the WiFi even when supposedly mirroring from a cell phone.
