On our upcoming trip we'll be going with a couple other families. I suspect that we'll split up on one of the days with most people going to HS and some of us going to Epcot. We will all be on the dining plan. If one of their children wants to come with us to Epcot instead of going with their family to HS can they use their dining plan credits? I know the children don't have charging privileges but do they have access to the dining plan credits? Or would one of the parents need to come with us?
