I thank everyone for their replies and suggestions.
To recap, at the end of my lovely 10 day cruise on the Carnival Venezia, I accumulated over 11,000 points and finished positive about $400. On the day I hit 10,000 points, I received an email from Carnival Players Club (rate code PXG) that I earned $2500 in cash from Carnival for playing over 10K points, which I don't truly understand how it works. If anyone can explain it, I would sincerely appreciate it. Thanks again
