Curious to see if hipmunk expands to other travel products. Tapping GDS systems for inventory should be relatively easy (ex any subscription fees). The challenge will be creating a UI that can correctly convey the value of those additional products. Airfare really only has a few value variables (price, duration, departure/arrival date, and stops) that are clearly objective. Expanding into other travel products (hotels, packages) and you start adding many more variables and subjective value.
