How can I book a pass to Great Tides Waterpark?

Booked guests can reserve a pass to Great Tides Waterpark, subject to availability, by logging into MyNCL account up to two days prior to sailing. Guests are strongly encouraged to pre-book, as availability onboard may be limited, and passes are not guaranteed once onboard. Guests who have not pre-booked may visit the Shore Excursion Desk during their sailing to check availability and purchase remaining passes, if available.
