Be prepared to get dazzled by Dubai. Everything in this second largest Emirate in the U.A.E. is super-sized, super luxurious, and state-of-the-art. A cosmopolitan metropolis, Dubai attracts the most seasoned travelers from the world over. You could catch a show at the Dubai Opera, take a 4×4 ride over rippling sand dunes, dine at an upscale restaurant at Jumeriah Beach, ascend the world’s tallest building, the Burj al Khalifa or ride a hot-air balloon over the Arabian desert.
