www.airbnb.com, featured in the New York Times allows you to find a creative solution to both. Simply put, people place their homes, apts, flats, mansions, tree houses (for real!) on the site. You can get a good deal and it beats any hotel by far. Is there some risk involved? I would say so, but you do have some reviews to look at and other factors to ensure that things go smoothly. Regardless, I love their website interface.
The two other places to take advantage of (if your a memeber) is AAA and Costco Travel. I found some pretty good deals on AAA.com and if all goes as planned, I will be saving $100's of dollars!
