I travel pretty regularly for work and where I’m at right now is beyond pathetic. It would be nice to compare users experience with internet speed when making a booking decision.
To add to that the overall internet “experience” could be a rating. Some places I stay have decent speed but they boot you off every 6 hours. Some make it extra difficult to log in. Some sneak access in as an optional extra. Some do all three.
It’s fine to ask the hotel if they have wired Ethernet in rooms before you book, some do.
Typically wifi, even in the best hotels, can get pretty terrible at peak times.
