Time out of POM parking garage with Celebrity priority (not self-) debarkation

I asked earlier about estimating time we'd be able to get out of the POM garage with self debarkation. We're arriving back in Miami on the Celebrity Eclipse on December 27th.

I now think we may not be able to do self-debarkation. We're in Conceirge Class and do have priority debarkation. What's a reasonable estimate for when we'd be able to get out of the garage, considering both offloading of baggage and clearing Customs and Immigration?

Thanks!

I would say you can be out by around 9:00 AM. But you just never know.
