Too much driving. Not enough time at museum. Eliminate stop at the beach. Wish the tour included a trip up the tallest building. I would think a tour company could negotiate prices and times with the building.
Personally I wanted the chance to see the incredible Burj Al Arab and Burj Khalifa that Dubai is created, which this tour allowed. However, you can't get close as to The Burj Al Arab as is suggested in photos, and to access the 124th floor of the Burj Khalifa we were told it would cost 200 each! Maybe because it was peak time or because we just turned up, but we walked away in disgust.
Our tour guide was informative, when asked, but reluctant to take us any further than where he parked the car. The aquarium at Atlantis resort Palm Jumeirah was brilliant, we just lost time trying to find our way to it from where our guide dumped us
