Booking a sleeping cabin on Hellenic Seaways

Travel dates, gender of passengers, port of departure and destination are 4 key pieces of information you have not furnished. When you ask such specific questions it's necessary for us to know these things. Generally, if you're booking a 2-person cabin you have to pay for 2 cabin tickets, no economy ticket holders allowed, so that means you pay €79 each or €158 total. Using the HS booking function be sure you've entered 2 passengers. That should give you the correct price for the both of you, not just one. If you are booking for a man and a woman and it's a 4-person cabin you either pay separately for one berth in an all-male cabin and one berth in an all-female occupied cabin, meaning you won't be together, or you pay for all 4 berths which effectively doubles the fare you would normally pay but allows you to be together.

Thanks Lee! It's for my girlfriend and I. We would probably just pay the extra for a 2 bed cabin. So we would just need to pay for 2 cabin tickets then?

It is per person not per cabin. If one of you buys a cabin ticket and one an economy ticket you will have a surprise when the passenger who purchased the cabin ticket becomes your roommate (same gender). That is the way this works, they will fill the cabin. You need to book a 2 person cabin and have the appropriate tickets.

That's what I needed to know. Thanks!
