Hi there Ms. B.,
We were not able to disembark until just before noon. Really a pain since we had to be out of the cabin by 9:00 I think (?), and all of the onboard shops were closed! I remember something about an "express checkout" though that someone else here might be able to give you more info. on. The transfer fee was $20.00 per person I believe....but not worth it in my opinion. We ended up taking a taxi after we got into Miami and saw the gaggle of people waiting for the RCI transfer..that ended up saving us a lot of time at check in for the cruise.
