I'm CEO/Founder of HotelTonight - thanks for the great comments and feedback.

We're working hard to add new cities to the app - we negotiate with hotels directly so this takes some time. Be on the lookout for Miami and Seattle soon. What other cities/locations would you like to see HotelTonight add deals for?

We're also planning multi-night stays and an Android/BlackBerry version. I'll post more updates soon.
