I could never get a clear answer on that when I was onboard (Dream) just last week so we were just planning to go to the sit down breakfast until we strolled through Cabanas at 8am and it was still open with tons of food. We were in no rush and sat there for a good 1/2 hour and food was out the whole time. I think Cabanas breakfast was one of the my kids highlights of the trip they were happy to get it in one last time...
