If you are in USA, the best thing I found was T-Mobile has at 100GB hotspot plan for $50 a month which each of you can get one.
I have faced this a lot, since I have been a digital nomad for 8+ months now. Other things I did: like downloading songs and movies on my ipad when I have wifi has saved me a lot of GBs. On windows there is a setting called "metered connection", which will make sure it does not download major updates etc over your hotspot.

This is an underrated advantage that the Apple ecosystem provides. I have a 2011 Mac mini and swapped out the hard drive for a 2TB SSD. I just keep everything downloaded on it and buy/download new stuff when wifi is around. At all other times, networking is turned off.
It connects to hotel TVs etc via standard HDMI. It has an IR port, so it can be controlled via remote.
The DRM'ed stuff has to reauthorize every month or two. It's a very low-bandwidth operation that takes about 20-30 seconds (and reauthorizes all your content). I share internet from my phone and a two-bar, no LTE connection is more than enough.
I even have the original box it came in, so I don't worry about damaging it when moving around.
I've considered this, but haven't pulled the trigger yet. The Skyroam is on T-Mobile I think, but like I said - so far that device hasn't impressed me.
I think the LTE iPad that another commenter suggested is the best option I've seen so far - that would be great to take calls on, and should leave enough hotspot data for other work on my laptop.
