Shopping Malls - Expensive stuff - Crowds - Traffic - Fountain
Tallest building in the world - very cool.
Think Las Vagas - without the booze; oh and no gambling or shows - or alcohol.
Can be easily missed and you won't miss any sleep.
Other ports on this trip include Muscat and a couple of others barely worth mentioning unless you want to tour a Mosque or go to a palace, hotel or yet another Mall.
