My wife and I just stayed at a preferred hotel last weekend and spent $3,000 and had a fabulous experience and would definitely return, BUT when I inquired about their loyalty program they told me to go online and register with iPrefer and submit my folio for points and membership. After submitting my folio and application for points, I got an automated email saying they do not reward points for stays before joining iPrefer. What? How was I supposed to know this hotel was part of the iPreferred network before checking in unless I was a psychic? I have been a lifetime member of every major hotel program out there, and never heard of iPrefer. If iPrefer's objective is to foster loyalty, it is doing just the opposite by penalizing a "new" customer whom I assume they would like to return (after all, isn't that the definition of loyalty?) BEWARE of iPrefer and put your psychic hat on before making a reservation at any of their properties.
