Check back often. Unfortunately, it does happen that some of the more popular shore excursions will sell out. However, cancellations may occur from time to time.  We recommend that you book all shore excursions as early as possible after booking your cruise and meeting all deposit requirements for each of the guests you are booking shore excursions. If an excursion is not available, you may want to search for alternate excursions within the same activity type or see the Shore Excursion Manager onboard to check for last minute cancellations. The option to wait list an excursion is not available at this time.
