I think some of you are making this out to be much more nefarious than it is. Nothing the OP said makes me think they want to pull a ruse, and I seriously doubt the schools include in their criteria that the school days must be the only opportunity for the trip that the family has. Hard to believe I see more cynical sourpusses on DIS these days than I do on Reddit.
I suggest letting the child make a video of some of the suggestions above to bring back for classmates to see; you might even compile it into a nice production when you return home. That might get her into it and provide some nice objective evidence that she was really learning about animals or countries instead of just riding Space Mountain all day. You might even be able to focus on things on her current curriculum.
