Hi! I am planning a trip and would like to do the River Runners 1/2 Day Raft (Bighorn) and Royal Gorge Bridge package. I had a Royal Gorge vacation book and wrote down all the rafting promo codes before I researched which company we wanted to go with. I must have written down the wrong promo code for River Runners (15% off promo code Gorge) as it is not working. Any suggestions as to how I could find some coupons? We are trying to go with the most economical package. Thanks!
