A family member from FL is coming to spend the day with us while we are at WDW. I called WDW-DINE to see if we could just add one adult to our reservations at the Akershus Princess Breakfast and at the Biergarten. They found a later ADR at the Biergarten for that evening for 3A and 3kids but could not add on to our AM ADR. Should I take this as gospel or continue trying to add one? Thanks for your help.
