Mine is 2016, so two years back.We were there last year, I think we were on the same cruise as Acquaduck, and we got to the port early and I don't remember it being crowded at all. We definitely didn't have to wait outside, and yes it was raining.
We got a taxi direct from hotel tivoli, and got there 10.15 am ish,
We had to drop our bags other side if the terminal to the photo above, then walk around and to the front.
When getting there firstly iirc the front door wasn't open, and a line developed fast, friends of ours were 5 minutes behind but down the queue.
Then they opened the door, circa 10.20 and we went into the small lobby, pre security scanners, its very small, they lined people up in queues, the seating went fast.
People were not happy as it was not in order of arrival.
Back to backers were in the terminal.
The back to backers left, and security opened for x Ray entry.
We went though in reasonable time.
Then checked in.
The terminal was fall quickly as per photos.
I know there was a queue outside and around, but as part walled not windows could see how far.
Embarkation iirc started at 11.30, there were some people trying to go in with concierge who were Platinum and gold and were kicking off badly, but were held back.
The boarding cards for platinum, said, " anytime ".
We had a big storm whilst in the taxi, and it was pouring down, on port arrival, eased a bit, and you can see some white clouds one direction and black clouds the other.
I think it rained on ship, but broke for sailaway.
