Had no contact with the supplier until 2 hours before the tour began. A little nerve racking. Guide showed up late and looked like he hadnt slept all night. Yawned throughout the tour. Guide was knowledgeable. The 5 hour tour ran much longer. At the 4.5 hour mark, we were dropped off at the Burj the last we saw the guide. We were handed tickets for the Burj for a time 2 hours in the future, or the 6.5 hour point in the tour. Spent a half hour at the Burj and it took an hour to get back to the ship. Total time ship to ship was 8 hours. Did see interesting things, but was over shadowed by the lack of Communications with local tour operator and the 3 additional hours the tour took.
