The Tech-Savvy Traveler @sorayadarabi professes her @thehipmunk love to @NYTimes Q. Do you use kayak.com a lot for booking? A. I do, but I use Hipmunk (hipmunk.com) a little more these days. It’s probably the best service out there for comparing what’s most affordable or the best time to travel somewhere. via travel.nytimes.com Thanks, Soraya!
