None of the coupons work for me.
I always get "he hotels in this location are unavailable for your dates and/or special rates. Try changing your travel dates and/or special rate request. For stays of more than 220 days, please call in the US 1-888-236-2427 or phone number for a reservation agent near you.". (PS: the hotel IS available at those dates, so this is related to the coupon code LNF/UAX)...
Booking thru
