We are headed to WDW in May - 3 adults and 2 children 2 and under. My husband and MIL would be good candidates for WDS Dining plan but I'm having gastric bypass surgery in Feb and won't be able to eat other than a few bites of a kids meal. Does anyone know if all members in a party need to get the dining plan or can we just purchase 2 (my kids aren't old enough).
