just an FYI, I was just able to make my dining reservations for chops on the Dec. 6 sailing of the Navigator, so if you are booked in that time frame you may be able to make yours as well.
Me too for Mariner at Chopps in Sept-what a great idea!! No waiting in line on boarding day to get a nice time for a great meal-no wonder we all like Royal Caribbean so much-very user friendly!!
