I've used it once on a stay at Lygon Arms in the U.K. and both the property and LuxuryLink performed exactly as advertised/promised in every respect.

However lately, I've noticed that the packages don't seem as keenly priced and often can be easily beaten elsewhere on the net, sometimes just by going to the hotel's own web page. Also, few of the auctions I've looked at get into a bidding contest, which probably is further proof that the prices aren't so great.
