"Rather than booking a regular hotel room, find an unique and interesting alternative through sites like airbnb.com for great deals on everything from tree houses to castles."
Stay in exciting lodgings like an ancient British castle for a nightly rate of $131, a mushroom dome cabin for $90 a night, or on a boat that will take you away from reality. I found some pretty good deals where I live, such as a $95 per night tree house overlooking the San Francisco Bay. Pick an exotic airbnb locale that's close to home to save money on transportation costs.
You need to spend some time searching, and even if nothing pops up, new rooms are being rented out all the time, so all you need to do is be patient and keep a vigilant eye out for unique accommodations!
