$18/person is quite steep, so I deducted 1 star. There's a one hour audio tour available, but honestly, despite the tremendously beautiful view, I don't think I can spend an hour there. You go up an elevator, enjoy the view, take pictures, and leave. And bam, you're poorer by a chunk of money, especially if you're going with company. $36 for myself and my husband, and I kind of wish it came with a little something extra. Or SOMETHING. Y'know?
