We do lunch now as well and we have done dinners (with larger groups who have an aversions to big lunches) and I honestly cannot tell the difference between the two meals. I definitely see the similarities - I'm always ready to roll out at the end of the meal and I can't finish one of the bigger beers at the meal. HOWEVER - that's not a problem and not many people know this. My husband did a cost comparison at our last lunch there and the big beers are a bargain compared to the other beers around World Showcase (and we only drink Bud Light around World Showcase). So, get the big beer and if you can't finish it, just ask for a To Go cup and one will gladly be provided. One of those beers will last me right up to Illuminations.
