Regarding the back-to-back booking of Amex Fine Resorts Hotels... I've done the linking thing too with two different cardholders, but recently, I was looking at doing it agin with DD26 (same last name) and I noticed language saying that you couldn't do this and wouldn't get the perks if caught. I thought they were trying to crack down on the practice, but maybe the language has always been there and I'm just noticing? Here's the language: "Back-to-back stays booked by a single Card Member, Card Members staying in the same room or Card Members traveling in the same party within a 24-hour period at the same property are considered one stay and are ineligible for additional FHR benefits (“Prohibited Action”)." I suspect it would be hard to implement with two separate bookings made with different cards--even with same last name--but I would be hesitant to link the reservations.
