I think seating flexibility may depend on the busyness level and CMs working. Last time we went was early August for a 1 PM lunch, and they offered us a choice of inside, outside or first available. The time previous to that was dinner around 5 or 5:30 PM during spring break the last week of March, and we were told that seating requests were not being taken, we would get first available. On neither visit did we actually attempt to request particular seating first; the information was imparted immediately at check-in. Also, we did have reservations for both visits. I don't even try Carnation Cafe without dining reservations these days, especially since we only visit during peak times.
