As a gesture of goodwill we have credited your Captain’s Circle account with a Future Cruise Credit of $25 USD per person. This credit will be available for you to use onboard any future Princess Cruise® booked by September 31, 2011.
Yes, this statement is very contradicting. Future cruise credit, and onboard credit two separate things. I think it's money credited for onboard use. I would call the number provided though and ask them to clarify the statement.
