I would hope to not get flamed here, but I booked one for this Sunday.
We have a short trip planned, arrive Friday, leave Monday. Fundamentally it's a total splurge and the cost is pretty laughable even for Disney standards, but I'm intrigued by the parts of it that can help subtly maximize our time, such as having a potentially semi-quiet spot where DS could maybe take a quick nap (vs going back to the resort), the reserved parade/fireworks viewing, etc. The other amenities are a nice perk. We aren't park commandos and enjoy a more leisurely pace actually.
Will make sure to report back on our experience.
Again, no flaming please, we all do Disney in our own ways!
