I recently went to roomsaver.com to find coupons for a trip to South Padre Island. I found one coupon for the Hilton Garden Inn for .99 per night based on double occupancy and on a walk in basis. I presented the coupon to the desk clerk and before even seeing the coupon she said "that is not our coupon and we did not authorize it nor will we accept it". She then told me to call the main office for Hilton Hotels which I did. The woman on the phone for Hilton said that I would have to contact roomsaver if the hotel I was at refused to honor the coupon. Roomsaver checked into it and called me back telling me that they had made a mistake and that it was too bad but nothing could be done. I was furrious that they had lured me into a 0.00 per night room with a great coupon and she said that the coupons encourage you to call ahead and make sure the rooms are available but they did not, it stated that it was on a walk in basis only and that you could call for reservations at a different rate. Do not trust Roomsaver.com for your room coupons or Hilton to honor them. Is there anything that I can do since I was seriously put out for our family vacation? I did not stay at the Hilton by the way, we went down to the La Copa Inn and had a very pleasant stay at a little less per night.
