we love dinner at cindy's royal table it has such ambiance in the castle & the food is good, we like the king & queen cut prime rib (& make sure to order/try the new cinderella slipper dessert, i heard it is divine & cant wait to try it on our november trip). dinner has a very different ambiance then breakfast & lunch (both are now plated character meals) so it depends on what you're looking for. dinner to us is more romantic especially during the fireworks but the character meal is fun & a chance to get pictures with cinderella & friends.
as for reservations like other disers have already mentioned they can be made 90 days in advance 407-939-dine & crt is very popular so i would definetly make an advance reservation (formely priority seating).
