Include everyone in your party, even infants When making a dining reservation, include the total number you will have in your party, even if one is an infant or someone who doesn’t plan to eat. The number has to be correct because of fire regulations. If you need to add to your party but can’t change the reservation online or on the My Disney Experience App, call 407-WDW-DINE (407-939-3463). They might be able to help you out.
