Buy a USB to HDMI cable to connect to your tablet.
I don't believe Galaxy Tabs have USB connections - at least I've never seen one that does. The Galaxy Tab HDMI adapter is what the OP wants.

The benefit of using something like Chromecast is that it is wireless. Your tablet can be next to you for actions like pause. Also it gives you choices from the internet such as Netflix and Amazon prime.
The ubiquiti stuff is great if the park has WiFi - not so much if the park doesn't have WiFi.
Chromecast is pretty slick. Of course, it requires WiFi to work.
