Like they said, booking your show reservations is a must but don't forget aobut your speciality dinner reservations too (if you plan on it). Breakfast in Central Park is so quiet and relaxed; watch the divers during their rehearsals; go on the Carosel and act like a kid; walkie talkies are great if one of you likes to sleep in while the other goes off to explore.
