Daily Getaways is a promotion sponsored by the US Travel Association and American Express, offering some amazing travel packages at a discount. You can find some of the 2012 offerings here, for example.
It looks like the promotion will be back this year, though two months later than in the past. A preview will be available on June 3, while the actual promotion will start on June 10, 2013.
While some great deals can be had, to be honest I found it more of a gimmick than anything else last year, given the limited quantities of packages and insane number of people competing for them. Hoping for better luck this year, and especially that Hyatt and/or Starwood points return at a reasonable cost!
