We were on the same cruise and took the Oceania tour Splendor of the Sultan. It was very interesting and gave an interesting perspective on the country. Anything connected to the Sultan was seen from afar as all his properties are behind walls . We visited a museum of his treasures and exhibits of his life as well as the Polo grounds, golf club an amusement park which was closed and a fancy hotel. We also saw some mosques and the countryside. Tourism is not well developed and cruise ship visits are few so infrastructure is not well developed
