I recently had the idea of taking the FireStick 4K Max that I bought ~1year ago for the living room smart OLED TV which is getting a little older, I had gotten ready to take it on a few trips I'm doing this year, thought I was being clever, unfortunately it died a literal week after the warranty, boot looping constantly.
I won't buy another Firestick again, it was atrociously add-riddled and often showing things inappropriate for the kids in the middle of the day, but if generic Android TV stick like that was available with good performance and all the necessary DRM levels, I'd probably use that.
For now, I will just carry an HDMI cable and use my laptop.
Unlike the sibling, I've never encountered a hotel with all ports blocked. But I have encountered hotels where there is no way to choose other ports. In that case, I've just unplugged their STB and plugged my FS in.
This was a bummer just the other day where my iPhone somehow (and I still don't know how) auto-signed into an amazingly fast wifi AP managed by my cell provider, but I was stuck working on crappy guest wifi on my laptop and could not get the laptop onto the better wifi.
