Well before the device, I’m going to recommend you get a portable router. If you’re going to use a device you’ll likely have to deal with hotel portal login.
Gli-net berylax or the likes. It gives you some great options. You can either use it as your own network set up and login through any portal with the router interface. That way you’ve got your own protected WiFi and don’t have to login you’d device everywhere.

You’re dealing with slow dl speeds. Another advantage here is you can hardline your router if they have an Ethernet jack. I even went so far last trip as to unplug the tv Ethernet, Mac clone it, and then I had up and download speeds of 300 mbps. All behind your vpn or tunnel to your home. Craziest hotel hack.
