I don't think I have ever been in a hotel that doesn't have a kettle, just seems weird to not offer one.
I cant help with the kettle part, but I can help with the pourover part. I use a Hario V60 drip kettle air (its not a kettle, despite its misleading name) for pouring while traveling as its resin so unlikely to break or dent, its extremely light weight, and can give a reasonably fine pour to a gush, if that's what you need. It does take a little while to get good with it due to it being so light weight.
I use a food safe thermometer to track the temperature, that way I do not care what kettle I use, plenty of reasonably cheap folding ones on amazon and the like.
