FWIW, the food at SoG ain't all that. the meal plan at SoG only covers the breakfast buffet( which is okay, plain, but okay) and the nightly Buffets..NOT Evergreens or Mangino's. Evergreen's..well let's just say every night after a day at the parks they got much of our money.. their teriyaki wings and key lime pie were my downfall...
the dinner buffets almost universally get mediocre to bad reviews.
of course I personally don't see the need to have a character meal each day, but as long as you are frugal with your other meal choices, you should be okay. there is a small fridge/cooler in the rooms and you can always pack lunch fixin's or even eat brekkie in the room as well. there is a small Exchange on site.
we always pay OOP for our meals as the Dining plan is waaayyyyy too much food for the two of us( we always share an appetizer and dessert) and I have never starved nor have I felt like we spent too much money.
In fact, many CS meals around the parks are large enough to split.
