Came here to recommend the gl.inet range. Folks love em on cruise ships for the same purpose as what you want.
I’m tempted to bring one with me to a hotel so I can bring a wifi enabled camera to watch my gear too, and not have to set it up with the wifi. If you need to authorise it with a web portal, often what you do is you connect with your phone (turn off random MAC), authorise on the phone, then connect to the gl.inet and have it spoof your phone’s Mac.
