For each stop there is many possible excursions, which you can either book ahead of the cruise or on board. We decided for two trips. A boat tour in Oman and a desert safari in the Rub al-Chali desert in Abu Dhabi. ###>For each stop there is many possible excursions, which you can either book ahead of the cruise or on board.
