Expedia has its own Expedia Rewards program that I have written few times. You can normally redeem $50 hotel coupon for 3,500 points.
Expedia Rewards now has limited time promotion for $5 coupon that required 700 points and $10 coupon requiring 1,400 points. This offer expires on May 17, 2014.
You can access Expedia Rewards here.
You can normally redeem 3,500 points for a $25 hotel coupon or $50 coupon only valid for VIP access hotels (limited time).
The points valued were inflated so badly last year that I really don’t take Expedia Rewards program into consideration at all when booking travel.
I do like, however, using Expedia for flight bookings and their hotel BRG (Best Rate Guarantee) program is fantastic. So, I do ended up with some points that I need to use every once in a while.
