Hello Kelsey,
How wonderful that you have your trip booked for next year. The Disney website is fairly easy to navigate. When you are in your reservation window of 180 days, simply select the restaurant from the
Dining choices, select your date and preferred time and then click "find a table". Available times will be shown and you will select the one you want. It does help to be flexible on your dining times, so rather than choosing a specific time, select the meal instead; breakfast, lunch or dinner. If you prefer, download the My Disney Experience app to your mobile device and you can make your reservations that way.
Advanced Dining Reservations are highly recommended, even for the Downtown Disney restaurants. You can make reservations at these venues the same way you would make them at any other Disney location.
If you need anything else as you plan your magical vacation, please let us know.
