Recently they've blocked selecting a hotel's address. I do so to look at the area or public transport options on Google Maps, but I guess too many people look up the hotel website from there and book directly.
Fortunately, you have more power than you think. Just don't do business with these companies. Picking a hotel and calling them directly always works for me.
One could also open the DevTools, Ctrl-F for part of the address, and copy it from the HTML source...
