We've done concierge lunch once, and the regular MDR lunch once, mostly to avoid the chaos/crowds and because we bring our own carryons onboard instead of checking them at the terminal. But I think we'll try either Marceline Market or the pool deck options next time. The entrees were incredibly mediocre and it felt like the service was really slow, my food was cold when it was served. Hoping with an early enough PAT, the buffet won't be too crazy. Maybe we'll just check our bags even though we usually just bring one carryon per person.
