I have an upgrade/change request attached to my upcoming reservation and lo and behold when I look online the exact resort change I want is sitting there waiting to be booked. I tried different things to get it to attach to my upgrade request (such as pretending to book it and taking it out of the system for a few minutes) without success. Got onto a chat and the CS rep tells me that the upgrade/request will only work if the unit showing on the site has been deposited by an owner, and in this case apparently the resort deposited the unit. Has anyone else run into this situation? She said she was unable to override the restriction.
