Has anyone done this? I'm meeting my daughter in Phoenix for a long weekend, and am considering. But, I'm so afraid of heights. Still, DH wouldn't ever do it (also afraid of heights), and I think I want to. Any advice for me? To clarify - my fear of heights is more when I'm on a ladder - and can see the ground directly under me. I get dizzy. DH can't go near the edge of a balcony to look over. I'm ok with that.
