Redeem your Thank You Points for $1,000 worth of gift certificates for Carnival Cruise line or Royal Carribean.

If the Thank You Points are all in your name, convince your spouse to apply for two Citi Premier Cards, using the double browser trick, for another $1,000 worth of Carnival or Royal Carribean gift certificates.

Otherwise, apply for the Chase Sapphire Preferred card for a $400 statement credit or the Ink Bold for a $500 statement credit (although the points might be more valuable transferred to an airline or hotel program, some people use them to replace cash expenses on a trip). Or, the Capital One Venture Card (10,000 point bonus) gives $100 reimbursement for travel expenses.
