After touring the area twice now - I think the average guest will be very impressed with the theming of New Fantasyland. But I think they will be searching for a little more substance. It really is just one pretty ordinary ride (with a fantastic queue) - a recycled Belle show in a more elaborate setting, fantastic looking restaurant, and gift shop. Storybook Circus looks great, but doesn't add much more than eye candy to already existing attractions.
Again, there is no denying that some amazing talent and creative minds were put to work on this (as well as money...and we know how hard it is for Disney to part with that these days), but average guests pay attention to details and theme less than fans. It's more of a passive experience for them, and I can't help but think the average family will be expecting a little bit more from an attractions/experiences point of view.
