I've never understood why Hamptons always require a code, but HGIs and Homewoods almost never do, yet the wi-fi is free at all locations of all three of those brands. Is there some roaming band of wi-fi stealers who target Hamptons and not other Hilton brands?
And over at Marriott, I've never needed a code for the free wi-fi at SpringHill, Residence Inn, Courtyard, or Fairfield.
