Sunshine Seasons has a very large dessert selection. (Strawberry Shortcake is to die for) if the kids are on DP, it should be the same selection of desserts. I didn't see a separate section of desserts, although I think they have a few of the healthy options WDW started offereing.. (grapes, cut up apples) things like that. Hope this helps.
I have ran into two different things so I guess it depends on who is ringing you up... the first time we got whatever dessert we wanted and the second time we were told we had to choose between dirt n' worms and a few other things but nothing that DD wanted.
