I am planning to go to both the Grand Canyon and Hoover Dam, thanks for the additional tips, Foy!

I'm making the trip in 7 days.. but have an eighth day cushion if need be.

I don't think I could eat a big steak in an hour, so I will probably plan to pay for that meal :) How much time do you recommend planning to spend at the petrified forest? Also have you found driving in the morning is better than at night? I can drive during any hour, but try to avoid traffic as much as possible.
