Finally, we took our suitcases and took a taxi to the port. The taxi, of course, was actually a boat. We sped away immediately!  

We continued further and further:

And here is the port:

And this was our liner - 

"Costa Victoria"

:

Our cabin was somewhere on this side:

We found where to check our luggage in and then boarded the ship. Everything was set-up like an airport; registration, customs, etc.  We also passed through a metal detector during security, where our carry-on luggage was checked.
I took a picture of this interesting fish in the port while we stood in line for registration.

Boarding the 

ship

took place between 2 p.m. and 5 p.m., we departed at 6 p.m.  
As soon as we boarded, our passports were checked and everyone was photographed. 
The cabins were not ready yet. But the dining points, swimming pools, and other areas were open for use. The cruise was an all-inclusive package, however this did not include alcohol.  Either way, it was a good start! 
Of course, we went right to the top and began to photograph the area.
There was a pool on this deck. To the right, you can see the port.

This was the view to the right:

Further to the right; the view was blocked by a liner docked in front of us.

We went to the other side of the liner, where we saw this very long road.  

It was hard to see the other end of the road. Both trains and cars used this road. Then, the cars were left here in the port. To travel any further, you had to cross the water. There was no road transport in 

Venice

.

Here is a closer look. A train was coming.

At 4 p.m. we were gathered in the hall to listen to a speech about the ship and take a tour.
There were nearly 2,000 people from 43 countries on the ship.

Stops: Ancona (Italy), Santorini, Mykonos, Athens, Corfu (Greece), Dubrovnik (Croatia).
We signed up for a tour with the Spaniards.
We decided to go on all the tours (250 Euros per person for 6 tours).

Anything that required payment outside of the "all-inclusive" package could be purchased by a bank card. We had to activate it and link it to the card we were given on the liner. To do this, there were special machines in the lobby. There was also an information desk onboard, in case guests had questions.   
Each evening we were brought the "ToDay" newspaper, which outlined all activities planned for the next day. This included both community and private activities or events.  

We stayed on deck 10, cabin number 10400, complete with a balcony.

This was the balcony in our cabin:

To the right, there was also a shower:

This was our floor's corridor. 

You can get to the right deck via the elevator. Everything around us shined like a mirror; sparkling clean. It was impossible to take clear photos because the ship's features were reflected off of the surfaces.  
This is a view from the top. The elevators were made of glass.  

Here is a view from the ground, near the elevators.

In one of the corridors, there was a model of the ship:
