Planning a long voyage
The voyage lists tell you what is on sale. These guides cover what a long trip asks of you before you go: the money, the paperwork and the practical questions. Each one lists its sources and the date we last checked them.
Year-long cruises: how to spend a year at sea and what it costs

World cruise visas and documents: what US passport holders need
A US citizen on a world cruise needs a passport book valid at least six months past the voyage with spare blank pages, plus visas or travel authorizations arranged in advance for several stops, such as Australia's ETA, New Zealand's NZeTA and India's e-Visa. Confirm each rule with your line and the government page before you sail.
