Im presuming as it says OV1 on the subject part, that you're embarking at Heraklion? If you are then heraklion port is really close to the port, a quick taxi ride and you'll be there. Then you go through the terminal building and keep walking through until you see the OV part, then you'll get your cruise card from there.
If it's Palma then the port is a bit further away, you get there,go in to the white, tent-like building and check in there.
Yes just follow the crowds & you will go through a terminal building with airport style check in. You didn't say your embarkation port but the system is universal wherever you go from. And yes all will be explained in your travel docs.
You are picked up at the airport (Palma or Heraklion)and your luggage already will have labels for your deck and cabin so they go into the coach and are taken on board from there when you reach the port. At the port you will be given your cruise card and have your documents checked similar to an airport check in. Then up the gangway you go (after waiting for everyone to have their photo taken !)I am off this thursday - happy days !!!!!!!!!!!!
I can only answer if you're cruise only going from Palma. We just jumped in a taxi at the airport, asked for the Port and showed the driver a picture of OV and away we went. Cost around 50 euro and we were dropped right next to the check in area. Bonus is we were not there at the same time as coachloads so no queue to speak of for airport style security.
There is a duty free shop as you board but remember you're not meant to drink your own on board.
