Wedding Certification

Dream weddings don't just happen, they're planned. Marriott Certified Wedding Planners are trained to help. After completing demanding coursework, each Marriott Certified Wedding Planner is qualified to coordinate weddings of all types, including ethnic and military weddings. Relying on experience, training, tradition and old-fashioned intuition, Marriott Certified Wedding Planners can help you determine an overall vision for your wedding and help you execute each detail. That includes setting an event budget; deciding on a menu; arranging table settings; and finding florists, photographers, a band and other entertainment for the big day.
