I found a great app on Facebook. If you Google 'Facebook Hotels with Me' you should find it. This allows you to book a Hotel in virtually any country in the World, and you can do it within your Facebook account. Not only that, you can also book it with your friends if you are all logged into Facebook. You can choose the Hotel together, rate it together, and there's even a chat box so you can discuss your choices in real time. Once you've made your choice you can then book it together at Hotels.com. This really is a cool Facebook app. You simply go to the app within Facebook and then you invite your friend or friends. You don't need to have the app installed on your own Facebook pages by the way. Just go straight to the app within Facebook. Once you have selected a hotel you get re-direct to the Hotels.com website. But it still feels like your in the app.... very well integrated.
