Since I would have a "salary" for the whole year, I would take four months off work and find an agency where I would pay MSC World Cruises.
To leave enough $ in my pocket and pay for visas and tours full of destinations, I would have to settle for a cabin with a window and an ocean view, and if I was determined to spend every cent, I might choose a room with a balcony - after all, I should enjoy 120 days 🙂
