Each reason is one
There are various reasons for you as a teacher to organize a study trip or a school outing. Are you going away with your class purely for the purpose of relaxation? Is it a trip to have the pupils get to know each other at the beginning of the new year? Or are you organizing a fun farewell trip for your seniors? The comforting atmosphere on board and the numerous activities on and around the water will make your school outing into a success. Relaxing on deck enjoying the sun, having a swim, visiting ancient towns, and dancing in a discotheque during the night.
In the same boat
Being together on board of a ship means that you will have to cooperate closely. Together, the group will need to keep the ship clean, go grocery shopping, hoist and lower the sails, and even man them. When you are together on such a small space, you should have some consideration for each other. Luckily, you are all in the same boat. It will surely be a study trip that will be talked about a long time after.
