Seek Las Vegas car rental for 5 days (October 2013 Monday to Saturday). Plan to drive to Grand Canyon for 3 days. For 2 person, standard or full size car, no mileage limit.

Should I select car rental in town or at the airport? I plan to stay on the strip but have not book yet. Assume most hotel has LV airport shuttle services?

Should I book for the entire week or just Monday to Friday to avoid the weekend crowd? I assume LV weekend must be crowded compare to weekday?

Which car rental agent web site or booking web site do you recommend for LV?

Is FOX in LV good enough? Do they have LV site outside airport?

Thank you
