I was hoping to use my SPG Amex 35k certificate on a one-night hotel stay, but I won't be getting that certificate until after March 5. The hotel I booked is on the list and going up in category, meaning the 35k rate will increase to 50k. Has anyone have experience with swapping out certificates with customer service?? I could in theory pay in full using points now, and then hopefully change the reservation to the free night certificate. Has anyone done something like that before?
Your thoughts are appreciated!
