Hi Theo and welcome to the Disney Parks Moms Panel.
It's always lovely to be able to answer a question from a fellow Brit!
Lunch at
Hollywood & Vine is served from 11:00 AM - 2:55 PM each day so, 2:55 PM is the latest possible time for you to make an Advance Dining Reservation for lunch at this particular dining location.
You will still be able to enjoy the lunch buffet of kid- and adult-friendly entrees like baked chicken, deli meats, hearty pastas and fresh salads with a reservation at this time and likewise, you will still be able to meet, play and dance along with friends from Doc McStuffins, Sofia the First, Jake and the Never Land Pirates and Handy Manny.
Advance Dining Reservations are highly recommended for all Character Meals and can be made online or by calling 0800 16 90 748 from here in the UK, up to 180 days prior to your visit.
Wishing you a magical holiday filled with memories which will last a lifetime!
Emma
