Semester at Sea is the best decision you'll ever make

Just do it. Four months on a ship that goes around the world?! When else will you have a chance to do something so cool? Every day is something new and exciting! You get the chance to meet people from all over the U.S. and all over the world. The professors teach super interesting courses in a wealth of different subject areas. The food is terrible (or was when I did it), but bring food with you and buy stuff in ports and you'll be fine. Go on as many excursions as possible, as they often get you further away from the port then would be feasible on your own. They can also help you get visas to secondary countries, because you can't leave the country on your own- you must be on an excursion.
