I was about to smart off about 'what alternative universe these Hilton properties are in,' but ...
now that you mention it, maybe it is true that "most" of the Hilton Family in the U.S. offers free Internet. Hiltons, Embassies, and most Doubletrees charge you for it (and it usually is slow and unreliable, in my experience).
But Hamptons, Homewoods, Garden Inns, and some Doubletrees offer free Internet (which usually is fast and reliable, again in my experience).
Conrad, I don't know, but the higher the room rate the more a hotel seems to nickel and dime its guests. But no matter, there are so few Conrads.
Considering how many Hamptons there are, yep, probly true statement that "most" locations in the Hilton family offer complimentary internet.
