Wanted to give my experience here as I boarded the Dream in Ft Lauderdale last Wednesday - no one checked anything.
We had a family with 3 separate PATs (11:45, 12:15 and 12:30). Our transportation got us there at 11:30, and we didn't have any other time we could get there. We were prepared to wait until 12:30 if we were asked to hold off until our latest PAT. We walked right in with no wait and no one even asking to look at our PAT forms. They were already calling multiple Boarding Groups while we were having our IDs checked.
Seems like they really smoothed out all the previous embarkation issues from December and earlier in January.
