Wondering if anyone has experience with modifying reservations online. I have a 7 night stay in early September booked. Reservation was made during the free gift card offer. The new fall discount is available for my room type for the entire length of the stay. It comes up in the modify reservation screens online. If I were to modify my reservation online to apply the discount, would the reservation number remain the same? Yes, trying to apply a discount but still remain eligible for the gift card. I'm on hold to try and do this over the phone so I can clarify things, but wondering if I could do this online.
