I paid nothing for an upgrade in my Platinum points account. I had a problem though with printing out the confirmation. Even though everything showed the correct info for the upgraded resort online, when I tried to print out the confirmation it printed out the original resort info. I called RCI and after a long time on hold the VC assured me he had corrected it - nope, still printed out the wrong info. He then said not to worry, he would fax a confirmation to the resort. I called the resort, and was told they had not received a fax but did have my confirmation in the system. It was so far my only upgrade, so I don't know if it's a common problem or a one-time glitch. Just be sure to get your confirmations printed out properly a little bit ahead of time and don't wait until ten minutes before you get in the car lol.
