An interesting "mashup" launched on a popular tourism portal at the global hotel index uses Google maps to power a search of more than 500,000 hotels around the Globe. At first glance the site offers a nice flash-based mapping interface... drill down a bit further though and get hits supplied via a google map. The presentation is really nice in this app, mouse over icons reveals more information and online booking is just a click away from your hits. This is definitely a nice commercial app using the Google map API... well done.
