What if you don't know? We are eating at more TS meals then we have credits for and I've kind of loosely figured what we'll eat to get the most "value" out of the credits. For example, one night we have reservations at San Angel, but I think we may just want to order a few appetizers to share as our meals (the appetizers appeal more to me than the entrees there). I won't know until after we're there and depending upon how hungry we are or what interests us at the time. Can I tell the server after we've ordered whether or not we're using the dining plan, or does that screw something up? I know they usually ask before ordering.
