I was just at Paddington Hilton a couple weeks ago. Broadband access is free on the computer in the lounge. I think the "purchase time" is for wireless access from the lobby area.

With Diamond status, I almost always get an upgrade there, always have lounge access, and last time had free breakfast too. London Park Lane always upgraded me to the Exec floor and had lounge access. Great to hear Paddington is moving the lounge.
