I am kind of curious about something related to this as well. At most any property, one can get free wifi as a Gold/Diamond by entering their hhonors login info. However, a lot of properties also have been giving out codes as part of the "hhonors welcome package" or whatever. Many times, I just use my hhonors info instead, and I still get on just fine. However, is the code supposed to be somehow connected to the free "premium" internet that Diamonds are supposed to be getting? Has Hilton corporate ever issued a statement (here or elsewhere) about the actual, official methodology that Diamonds are supposed to employ to access this premium offering?
