If you want to do Fantasmic, the Blue Bayou dining package would be worth it to get a good spot and to be able to sit during the show (most other areas are standing only, but Blue Bayou you get a cushion and get to sit). If you are not doing Fantasmic, the atmosphere at Blue Bayou is fun (the POTC boats going through), but in our opinion, the food is a bit so so, and overly priced for the quality you get. It is very dark in there, so if either of your kids is sensitive to that, it could be an issue. When DD was those ages, she usually fell asleep on the table before the meal was over, but she did get a nice short nap which got her ready to go again! If you are not going to do Fantasmic, I second that Café Orleans is great. We had given up Blue Bayou entirely in favor of Café Orleans, until DL got rid of the Fantasmic dessert package and went to Fast Pass and the dinners. Now, we feel like we are kind of stuck back at Blue Bayou!
