Does anyone have any experience with the hilton 15% off cert for UA, it is good until the end of Feb. Have been trying to apply it to several MR's that I want to take, but it always shows that it has been applied and the price is the same as before they applied it. AM I MISSING something???? I even tried to go all the way thru the booking process and then apply it, but it doesn't work. Had the same experience with the TED anniversary discount cert also..
any help.....thanks
