If you change him up to an adult, his entire package turns into an adult package...Including the extra cost for adult ticket AND the extra cost to possibly having another adult in the room ( no idea why THAT is, because she's 7 and the room cost shouldn't include her in as an adult? But, that's what BOTH ladies on the phone said). We spent about an hour and a half on the phone today (2 separate calls) to get that info. The cost of the adult dinning plan is much higher than the kids per day. For us, there are certain meals that we can order and share with our child, so she'll always have plenty to eat. But, most Disney kids meals are pretty lame. I think they are going to NEED to up their food game if they're going to force the kids to order from the kids meals at QS locations!!! My daughter won't like eating the same hamburger, chicken nuggets/strips, mac N cheese or hot dogs 2 meals a day for almost 2 weeks. That is just not going to work for her. We actually like the taste of food. The kids meals there are lacking in flavor and options all around.
