Start your full-day tour of Dubai in the marina district and marvel at the manmade Palm Jumeirah island. Go to the Atlantis the Palm Hotel, home to the sunken chambers and submerged ruins of the Lost Chambers Aquarium. Continue to the world's tallest building and enter the Burj Khalifa next to Dubai Mall to take the high-speed elevator to the At the Top observation deck. Get panoramic city and desert views through the floor-to-ceiling glass walls. Next, come face-to-face with sharks, stingrays and other marine species with an entry ticket to Dubai Aquarium and Underwater Zoo. End in the downtown area of Dubai Mall, where you can shop and eat at leisure.
