When you book with a Four Seasons travel advisor to plan your Four Seasons Yacht vacation, you get insider guidance on every detail—choosing the right ship (river, ocean, or expedition), the best stateroom category, and must‑do excursions. We have the info on current promos, handle waitlists, secure dining and spa reservations, and make sure you get any eligible past‑guest or early-booking savings—perks you won’t always see online.
