Find the side entrance to the ferry (usually right next to the gate where the cars enter), mind the traffic and get on board. Each passenger should have their own ticket in hand as you step on board because an officer will take your stub and direct you onward.

Food on the ferry can be expensive so don't order without checking the prices first. A dish with meat can cost you 12 euro at the self-service restaurant, but a spaghetti dish can be half that price. If you are on a budget, opt for the sandwiches and pies sold at the bars, or better yet, bring your own food abroad. No one will complain if you eat your own meal at the bar or on the decks.

In terms of entertainment, the options are few. All ferries offer wireless internet for a fee (usually 3 euro per hour) and connectivity is good at the designated hot spots, but intermittent elsewhere, including cabins. If you rely on Mobile Internet for your connectivity keep in mind that there is no 3G in open sea and GPRS internet speed will be painfully slow. Many ferries have an 'internet corner' with available computers on desks that you can use for a fee.

Cell phone connectivity is usually good between islands with very few dead spots in open sea. If your route takes you close to neighboring countries (Turkey, Albania, Italy) make sure you are not connected through a foreign network that kicks in high roaming fees for your account.

There are electrical outlets in the hallways and lounges throughout every ferry (220V) that you can use to charge your appliances (computers, cell phones and such).

All ferries to the Greek islands are similar in other amenities. They all have a couple of bars inside and at least one by the pool, an arcade where young adults can play electronic games, a kid's play area for younger children, and a couple of shops with gifts and apparel. You can get snacks and magazines in these shops, but not newspapers. These shops have limited hours of operation and they are not open for the entire trip. Ferries that travel between Italy and Greece even have a casino aboard.
