IMO, no. I thnk it is very expensive and padded with unnecessary addons, the requried picture, etc.
I miss the days where you could have dinner in the castle without characters and have a good meal.
For the 2 credits each, you could do the story book princess meal and another character meal.
That being said, if your girls are die hard cindy fans, it could be worth it to you. (Although you can see her at the GF or in toon town without the meal)
If you go, let us know how it was when you get back.
Happy planning!
