If the OP and his wife are credit-worthy, they have enough time to get four free nights at the Hyatt Paris Vendome by getting the Chase/Hyatt credit card and charging just $1,000 to each card. @:-)
If more than four nights are needed, the Chase Sapphire Preferred card earns UR points that can be transferred to Hyatt Gold Passport. But I think you need a lot of GP points for each free night at the Vendome.
