I have received a few upgrades but have run into a problem with the confirmations when the upgrade involves a resort change - each time, I received an email from RCI about the upgrade, and in my account it would show the correct unit as the upgrade but when trying to print out the confirmation it prints out the original resort. The first time it happened I figured no problem, it's "in the system" and showed up at my upgraded different resort to be met with blank stares and no reservation - spent time on the phone with RCI to get it worked out, and it caused a lot of frustration with the staff at the upgraded resort. Since then I have gotten a couple more upgrades, and each time was the same situation with the confirmation, so I get online with chat and have them initiate a proper confirmation. It takes some time so I do this a couple of days before check-in. The last time, this past October, the resort I was upgraded into said they had me as a "no show" for the week before and nothing for the actual week I was there. I definitely was happy to have the correct confirmation in hand!
