I read the reviews prior to sailing, but took a chance any way. I knew somewhat what I was getting myself into. I have to say, some of the reviews are true, some I didn't witness.
There were long lines in Port on Embark day, but we sped right through them. They were very fast there. we were on the ship within 30 minutes.
Debark day was the same way. We were off the ship in less than 30 minutes.
