Hi there, Alejandro!
If you've already made your package reservations, you should have either received an email if you booked on the Walt Disney World website or through The Walt Disney Travel Company. That final receipt will have your
Disney Dining Plan information listed if you purchased it.
If you're still in the process of making your reservations, you should definitely see the Disney Dining Plan in your cart if you chose to add it to your package. There is a place for you to select that you want it to be added, so just be sure that you've checked that because it will not automatically be added in.
Your Dining Plan entitlements may not show in your
My Disney Experience online profile until you've checked into your Resort hotel. As long as you've got the plan on your reservation, you should be fine. If you are having trouble locating your confirmation paperwork, just give a Disney Cast Member a call at 407.W.DISNEY [934.7639] and they will be happy to assist you by pulling up your reservation.
I sure hope this helps, Alejandro!
Wishing you a Pixie Dusted vacation!
