Carnival Celebration Arrival time anomaly?

[CarnivalRich]

I’m platinum status and every cruise I check in right at midnight and all arrival times beginning at 9:30 are available When we checked in for our cruise 2 weeks ago right at midnight on the celebration the earliest time was 11am. Nobody was able to pick an early time, everyone that was diamond or platinum in our Facebook group was questioning why 11am was the first time slot. Has anyone else seen this before?
