I called my travel agency (Cheap Caribbean) to see how much it would be to upgrade to a one bedroom suite for my stay next month. I was quoted $54.10. I didn't upgrade at that time as I wanted to confirm with my husband. I called back yesterday, and now the same upgrade is $768!! (no that is not a typo!) I called fiesta directly as CC recommended. The woman at fiesta told me that I can only upgrade once I arrive on the resort. Has anyone upgraded on arrival? What kind of rates did you pay?
