I've used FW for a long time now for coupons and Cash Back and want to give back. Hope I do this right!
I have been looking for La Quinta promo codes and Cash Back, etc. only to find very little, as far as sales, Cash Back on FW, CitiBonus cash, or Shop Discover. Don't waste your time looking because it's not there! These, however, are codes that work - I have used them:
NEW for very beginning of 2013
NEWYR10 also works, same dates
BY THE WAY, I also used my Discover Card to make the purchase, which has a two week or so window in which they are giving double Cash Back for all purchases (2% for mine (Discover Open Road)). I found this to be the best way to receive the most discounted room and the greatest Cash Back, as compared to using Travelocity, Orbitz, Expedia click thru's and any code I could find.
Also, I'm going to look at Hotwire a day or two before my trip to see if the discounts are enough to lure me out of La Quinta (I like my pets with me (always welcome at La Quinta), but I'll budge for a much better price). Hotwire has click thru's here and CitiBonus Center and ShopDiscover, as well, so maybe!
