It's not bad. I've used it before, but I always carry a travel router (or two) for my other devices. I find it easier than trying to use a Fire stick to log in.

If you're connecting with the Roku sans travel router, you power it on, pick the WiFi network you want to use like normal. It'll try to connect. Some hotel networks now are letting Rokus through without signing in. If it can get an IP but can't see the servers it wants, it'll prompt you to go to Hotel mode. It then sets itself up as a wireless repeater to the hotel network. You connect your phone to the Roku's WiFI AP, go through the hotel login screen, and the Roku functions as normal. Not really a hassle at all.

I travel with both a Gl.Inet Mango ($20) & a Gl.Inet Slate travel routers. Most people would probably be perfectly happy with the Mango. If you're doing VPNs or need 5GHz and gigabit ports, the Slate is the better choice. I like the Gl.Inet travel routers for many reasons, but the best feature is that their WiFi section is set up like mobile phones' in that it will remember multiple networks. I usually stay at Marriotts, so many times the router automatically finds the right WiFi and connects to it.

With a travel router, the procedure becomes: Power up the travel router, power up the Roku. All of my devices are already paired with the travel router. I just point the travel router to the hotel's WiFi with my phone and all of my devices magically start working. It's a beautiful thing.
