No. Lumiere's on the Magic and Triton's on the Wonder serve a sit down breakfast every morning (it's limited choices on the disembarkation day though). Open seating for all except the last day. You can also have room service except on disembarkation day. On the Magic, there is also a scheduled character breakfast in Parrot Cay. This is a served breakfast, unlike the normal buffet in Parrot Cay.
