Welcome to planDisney, Dylan!
You're going to have a wonderful time at The Most Magical Place on Earth this summer! Don't forget to pack your sunscreen, fan, umbrella, and all-rubber shoes to be completely prepared for the sun, heat, afternoon rain, and puddles!
Currently, to reserve a vacation package with a
Dining Plan, you must book directly with the Walt Disney Travel Company online or over the phone. Costco travel packages are not currently offering dining plans, and they cannot be altered to include them once your vacation is linked to your My Disney Experience account. As Costco would be acting as your Travel Agent, you would be welcome to reach out to them to see if they have any potential Dining Plan offerings that could be added to your trip, but you would not be able to add the Dining Plan online or over the phone with Disney World directly at this time. I would recommend weighing whether getting the Dining Plan is more or less important to you than the savings you'd get if you booked through Costco.
I would like you to know, though, that occasionally
Disney Gift Cards at Costco will be discounted. Check for these on your next outing or on Costco's website. I've seen around 10% discounts on Disney Gift Cards offered at Costco at different times throughout the year. This could be another way for you to save on your upcoming trip!
If you have any additional questions before your arrival, Dylan, we would love to hear from you again at planDisney!
See ya real soon,
Allyn
