This isn't really a MR Tool, but as I recently mentioned, Best Price Guarantees can work wonders when you're on a trip in terms of saving $$$ on hotels. Check out http://www.expedia.com/daily/promos/...sp?rfrr=-36054 for a new Expedia promo where they give 15% off 2 nights & 20% off of 3 nights for November & December stays, with purchase by 9/15. As most hotels verify within 24 hours, if you find one that has a best price guarantee, submit a claim by 9/14 & print out a copy of your shop page. Most of the hotels & markets I looked were individual hotels, not chains, but some were chains.

This may be beneficial if you've got some stays coming up in Nov/Dec.
