The issue is that it is a premium over another package, not the base room rate, so we don't know the total additional amount.

There is no reason for even a non-Diamond to buy a premium package to get breakfast as FHR and Virtuoso rates (both typically lower than rack) both include it. These prices also typically get a one class room upgrade and some other amenity, like a free lunch one day.

So there isn't enough info to really answer the question conclusively.
