I wrote my entire novel in an interior cabin
I booked a fourteen-night transatlantic crossing on MSC Seashore specifically to write. Interior cabin 7220 was my office for two weeks. No window, no distraction, no wifi (I intentionally did not buy the package). I wrote from 6am to noon every day, ate lunch, walked the ship, read in the afternoon, had dinner, and slept. The cabin was a cocoon. The darkness helped me focus in ways I cannot explain. The hum of the ship became my white noise machine. By day twelve I had written 68,000 words. The novel is being published next year. My editor asked where I wrote it and when I said 'an interior cabin on a cruise ship in the middle of the Atlantic' she laughed. The cabin cost less per night than my apartment rent. Best investment in my writing career.
