My husband and I would like to visit the great canyon on November 29. We will be travelling from Las Vegas and have only one day. We have never been there before and would like to know what are ‘the must see’ points of it. Also, for the first timers, is it generally recommended to take a bus tour or rent a car (renting a car is much cheaper, however if there is a great risk of getting lost or missing great places we would definitely take a bus tour). Any tips or comments would be greatly appreciated.
