Hi, Yvette, If you plan to spend an evening in a certain theme park, that is where I would plan to have dinner. That way, you won't feel rushed during a meal. You can enjoy your dinner, walk outside, and experience the awesome shows that are planned without rushing from park to park.
What my family likes to do is plan a dinner on the early side, then when it gets closer to fireworks or parade time, we grab a snack. This keeps them occupied while waiting and gives them a little boost of energy!
When you reach your 90 day booking window, make your dining reservations at 407-WDW-DINE (407-934-3463.) Also, keep checking the
HERE for the park hours to be updated as you get closer to your magical vacation. Have a super time with your family!
