I have had mixed experiences with embarkation at Terminal 25 at Port Everglades for post-shutdown sailings, usually arriving 11:00 - 11:30.
One time (Apex, November 2022), there was strict enforcement of lines for various boarding times, on others (Beyond 2023, Ascent 2024), there were no lines at that time and pax could enter the terminal as soon as they arrived. Not sure of wait times once in the terminal, as we were in the Retreat and had separate check-in.
For my upcoming cruise in AquaClass on Silhouette, I will likely arrive at the port around 11:30 for an assigned 1:30 check-in time. I plan to hangout outside until lines abate, then politely ask port workers if I might check-in ahead of my assigned time, provided there aren’t people waiting.
