We did the "high" tea at the Burj and loved it--it was worth every cent just for the experience (and besides, the food was great--a good substitue for lunch). We also loved the HO HO bus, but it was hot and noisy, I'll have to admit. You might be able to see everything from a private car, but I don't think it would be as much fun. Our favorite thing in Dubai was the Desert Safari--don't miss it!!
