Forgive me if this has been recently posted or if I'm on the wrong board. Has anyone taken a Hoover Dam tour from Las Vegas? Is there a particular company worth using? I see Presidential has a package around $300+. Would renting a car and making the drive ourselves be a better option? If we rent a car, should we just rent at the airport the day we get there or would it be possible (without much hassle) to rent later in the week?
