I got a travel site that got up to 2,000 visitors a day before Panda. I am currently improving it. For some reason, I never thought to monetize with a hotel affiliate. I have no idea about the current state of 'hotel booking'. Is there a good affiliate out there that offers good rates for people referring "travel customers" Perhaps do I want to be an EXPEDIA or Hotels.com affiliate? It would be cool if there was an API (like groupon has) in which i could provide their site with a zip code and the widget could display 'hotel bargains' for the region in question. Ideas? Thanks!
