I have a VoIP phone I occasionally take with me when traveling. I did it more years ago when international cell phone rates were silly, but there are still times I need more functionality than a cell phone can provide for work calls. The phone does not allow you to go out to a website to authenticate. Most upscale hotels have an engineer onsite who will come up and add the MAC address to their system for the length of the stay. This way it stays connected and I do not need reauthenticate repeatedly. In a few instances there will be no engineer onsite and it has to be done via telephone with the company who manages the hotel internet. When they see the phone they understand that there is no work around. Would they do it because you simply don't want to re-login on your laptop, I have no idea ...
