I would assume with the transformation to Rapunzel's Royal table, that embarkation lunch will be at Lumiere's now, saving the surprise of Rapunzel's until you dine there. On the Wonder, they have moved lunch to Tritions when they put in Tiana's place and it is no longer a buffet lunch and is a menu lunch. If your are looking for endless food of a buffet, then would suggest you go to deck 9 for the buffet. if you want a sit down relaxing lunch, then pick Lumiere's
