1 – DO have all of your information set up in My Disney Experience in advance.
This is definitely important. You will need to create a free My Disney Experience account for your Disney World vacation. Once you do so, you will want to either create profiles for everyone in your party, or have them create their own account and link yourselves together. This allows you to add everyone to the party when you create the reservations. You will also want to go ahead and link a credit card. A credit card is required to be on file for all dining reservations, so this will save you time and hassle. If you have all of this set up will you be able to make reservations without stopping to get all of these things set up.
