My daughter was 4 when we went to this experience and she loved it! In fact, she is now 7 and we are planning another trip, when I asked her what she remembered about our last trip and would want to do again...Mickey's Backyard BBQ was top on her list!
Sure the food is average camp fare...chicken, hot dogs, ribs, etc, but it's not really the main draw here. Seeing your little one hug and dance with the characters is wonderful and worth the 2 dining credits. Plenty of photo ops here!
Also a huge draw for my girl...the endless and all you can eat popsicles. Normally its a one dessert rule..but with all the dancing, I let her indulge a bit and she burned it off on the floor!
As an adult, the inclusive beer and wine was a hit with me, especially since Disney is driving! If you have time after the dinner, head down to docks to watch the Eletrical Water Pageant.
