The suggestion of a Roku is a good idea, HOWEVER, before getting a Roku I'd suggest you check out the Amazon Fire. Functions similar to the Roku but I find it easier and better to use ESPECIALLY if you are a Amazon Prime user and can access a lot of the free stuff. I personally think the picture is sharper on the Amazon Fire. Frankly, I use mine primarily for Netflix and due to the small size of the unit (about the size of a large deck of cards)and a single HDMI hook up, plus power. Also, it has a remote with it that can use voice control for finding movies, actors, etc. Still need good wifi to do proper streaming. Any speed of less than 1.5 to 3mbps will make it VERY hard to watch videos on a smart tv, a Roku, or Amazon Fire. Check the speed of the wireless each time you make a new 'camp'. I use speedtest.net but on smaller displays you might want to try www.bandwidthplace.com
