Hi Nicola and welcome back to planDisney.
I have just telephoned the Walt Disney Travel Company (www.disneyholidays.co.uk) on the Disney Resort Hotel Reservations number, listed on the Walt Disney World
Phone Directory, to check this for you.
I was informed that all modifications to existing bookings, including the addition of a
Disney Dining Plan (to an existing Hotel + Ticket package) must be made at least 8-days prior to your arrival date.
If you made your booking through a different, third-party travel agent, you will need to contact them directly to check this as their booking terms and conditions may vary.
Top Tip - Be sure to check out the
EPCOT International Flower and Garden Festival which will be taking place during your visit. Not only are there the most beautiful topiaries for you to admire throughout the Theme Park, there is also lots of delicious food on offer from the Outdoor Kitchens and, a stroll through the whimsical butterfly garden, is just the best way to enjoy the start of Spring, in my opinion.
Wishing you a magical holiday filled with memories which will last a lifetime!
Emma
