I'm trying to identify which London hotels do not require a password for wifi. Most require a name and room number or honors code. This works fine for my personal laptop, but not my work laptop and I'm planning to work for a week. I recall a few don't. Doubletree Riverside, perhaps?

I think my alternatives are working off a mobile hotspot from my phone and can get a UK sim to do this. I know this not a tech forum, but if people have other ideas, I'd be v grateful. Thanks.
