So I've tried to help with the
free dining vs room-only question.*
The image shows nightly free dining savings (compared to buying it for cash) by family size and age structure.
Find the number for your family. You'd have to do
better than this number per average night on the room-only discount to want the room-only deal.
To figure your room-only potential savings, get your average undiscounted nightly room price and multiply it by the expected room-only discount of .30 for mods and between .25 and .35 for deluxes. (The range is because Black and I suspect that we'll find deluxes at several discount levels.)

*Only for moderates and deluxes--the "quick service" prices are different, but even so, free dining is always better at the values if you are in a 4-person room...
