There are moments that feel similar like 12, 17, and 18, and the stretch of 5-7 is watery, but there are plenty of holes that aren't similar, like the opening stretch. I really enjoyed playing the course, but I did not enjoy the three-week bout with heat stroke and poisoning I got from walking it in 105 degree weather. I drank a glass of ice water almost every hole, and when I got done I had to lie down with an ice pack on my head for two hours and was still sick/dizzy/getting weird headaches for three weeks. If you go, and if it's close to 100 degrees or over, do everything you can to stay in the shade as much as possible and hydrate, hydrate, hydrate. Ask Dick Daley - heat poisoning is no joke. In heat like that, there is nothing wrong with taking a cart simply for the shade and so you don't over-exert yourself. Of course a twenty-something spring chicken is going to have it easier than a forty-year old lawyer, but either way, the heat in the desert in summer can get dangerous.
