Marriott's Look No Further Rate

I am constantly searching online to find the best deals out there.  I always learn something new.  I just wanted to explain how the Look No Further Rate works with Marriott. 

1. Book a room with Marriott.  It needs to be a refundable rate--no cost to book
2. Find the same room, dates, hotel etc on a different site.  If you find it for cheaper--even 1cent cheaper you are in business
3. Within 24 hours of booking through Marriott submit a Look No Further Rate form (google it and the form with come up)
4. With 24 hours Marriott will respond to you and not only match the rate but give you 25% off the lowest rate you find.  They will automatically adjust your reservation

I can usually find a lower rate for most hotels.  Here are a sample of a few that I have found:

• Newport Beach Coast Villas.  Marriott Rate:  $324 night.  Found it for 323.53.  Adjusted rate:  $264.75.  (for 7 nights that is quite the savings)
• Marriott University Park SLC.  Marriott Rate:  $89.  Found it for $79.  Adjusted rate:  $59.25.  (stayed 2 weekend nights and used a Buy One Get One Free Coupon so each night turned out to be $29.25)
• Atlanta Northwest Marriott.  Marriott Rate:  $109.  Found it for $89.  Adjusted rate:  $66.75
• Renaissance Las Vegas Hotel.  Marriott Rate:  $109.  Found it for $92.  Adjusted rate:   $69 (I will use a BOGO weekend night making it $34.50 a night)

These are just a few of the great rates I have gotten.  To find the lower rates I just use search engines like orbitz, travelocity, dhr, easyclicktravel, bing, etc.  It almost becomes a game on how cheap you can get the hotel rooms.
