I just booked our vaction for 2009 directly through Disney cruise lines.
We got great inside rooms on deck seven at $449 per person for the 4 day Bahamas cruise in October. Great room selections for fall of 2009.
I don't know how old your grandchild is. But, Disney Wonder is excellent for persons of any age. My grown sons are psyched for this ship has something to offer everyone; child and adult alike
