I'm unable to download books using the hotels wifi. I was able to last year with my Fire 8 now unable to with it or my Fire 10
You need to contact whoever provides tech support for the hotel. That's not an Amazon issue from the looks of it. Hotels do a lot of strange, needless nonsense to muck uop "free" wifi. Fire up the Silk browser and see if there are terms you need to agree to first.
If it needs Flash to run their sign up, and a lot of places still do, you are out of luck.
