How To Use a Google Chromecast In a Hotel Room?
How To Geek has a very interesting article on this here:

Out of their proposed solutions, my personal preference goes towards deploying a travel router (described in the middle of their article; I am quoting it here below):
Most modern hotel rooms have Ethernet jacks. In an age when everyone is connecting wireless and the bulk of a hotel’s security efforts are focused on the wireless network, Ethernet jacks represent a sort of portal to Narnia where the data flows free and fast. In our experience the Ethernet jacks in hotel rooms are very rarely secured in any fashion and you can simply plug in a device and go.
How does this benefit you in your quest to get the very Wi-Fi only Chromecast online? It benefits you because you can bridge the Wi-Fi gap on your own terms by using a travel router. All you need is a compact travel router, an Ethernet cable, and you’re ready to rock. Just plug in the portable router to the Ethernet jack in your room (you may have to steal the port from the cable box or other networked device in the media center, but we won’t tell), fire up the router, and connect to the router with your smartphone, tablet, or computer to configure the Chromecast just like you would at home.
In fact you can even do a dry run at home where you get all the configuration done ahead of time (this way when you plug the router and Chromecast in at the hotel they’ll automatically start talking to each other).
Although its rare, if the hotel does have a login/authentication splash page for Ethernet users you can simply visit it with one of your devices (while connected to the wi-fi router). The router has a single IP/MAC address and doles out access (just like your home router) to all the attached devices. Once you accept the terms of agreement with one device through the unified access point the security system will let anything connected to the portable Wi-Fi router, including the Chromecast, pass through just fine.
This is the technique we recommend as it works in practically any room with an Ethernet jack and, if you do the initial setup at home, is essentially just plug and play. You can go from no Chromecast to Chromecast access is less than a minute. This is also the only technique that allows you to use the hotel’s data network in the face of (all-too-common) AP isolation.
Easy concept, travel routers are about $30, plug and play, many Ethernet ports in hotel rooms nowadays.
