The ROL dining package, for which dining plan is allowed at tiffins, is $67.00 adults / $26.00 children. So I think it is quite likely the 2nd tier FOTLK package (the one without the Safari and champagne) will be offered since that is $74 per adult and $29 for children, but but the 1st tier would not since that is significantly higher cost at $99 per adult and $49 per children. Though on that note, I think the fact that the basic FOTLK packages is more than Rivers of Light suggests Disney has thrown in the towel and is admitting that Rivers of Light is a total bust.
Has anyone else noticed that the menu described on the disneyparksblog post is significantly different from the regular Tiffins menu? I am trying to figure out if that means the regular tiffins menu is changing (which would be lame; I mean, shrimp n grits and filet & lobster are hardly African cuisine), or if this is a menu unique to the package and Tiffins will still offer its usual yumminess for a la carte guests.
