When we were there in '98 our oldest son (14) wasn't and still (at 20) isn't a big breakfast eater. We were able to order just a bowl of cereal and toast for him. I read recently they still have an ala carte menu. Also, the buffet is fairly inexpensive, like $7/adult, so you don't feel like you're getting ripped off if you eat a small breakfast there. Someone on another SOG thread asked about what was available in the AAFES store and the answer they got was small boxes of cereal and milk were sold there so you could do breakfast in your room also.
If you go to their webpage you can contact them and ask about ala carte and what is available otherwise.
We'll be there Nov 6-12, 2005 but I'm ready to go now.
