The main difference between Nowcation and Expedia is that Nowcation helps you find your destination. With Expedia, Orbitz, and other travel sites, you have to know where you want to go before finding deals.
I mean....on expedia, I have to query destinations individually as if I know where I'm going....this just shows me the options from my departures point of view...I love it!
if expedia and any of those travel sites had a UX update to something more elegant, more intuitive, and overall a more pleasing experience, wouldnt that be a good thing?
