When I make reservations at many Hilton properties, at the end of the process I am offered the option to purchase an upgrade. But upgrades are supposed to be a Diamond/Gold benefit. I don't purchase the upgrade option, but when I get to the property I am sometimes told no upgrades are available because "the hotel is full". If Hilton is selling the upgrades in advance, often at nominal rates of $10, $20, $30, until there are none left for Diamond/Gold members who already have confirmed reservations, are they not being duplicitous in offering elite members an upgrade benefit? If Hilton continues this practice, is it really worth working toward elite status? I would be interested in hearing other milepoint members' experiences and how you handled the situation. At Hilton®, Conrad® Hotels & Resorts and Doubletree®, choose from: A space-available room upgrade, including breakfast.** You will be upgraded to an Executive Floor room (where/when available) at time of check-in. If an Executive Floor room is unavailable, you will be upgraded to the next best available room from the room type booked.
