Certainly not an option for me or family, unless something changes in my financial future. However, could see this working on a small scale, and it would certainly be worth the effort on Disney's part. You could certainly get a lot done and leave the parks with a full belly, a good buzz, but a lighter wallet.
I think it's a different market than a wealthy family coming on a 10+ vacation.
This is more along the lines of a wealthy family that can sadly only get together for 1 day, or that mega family reunion.
