It will be our first time to vegas in april and we would love to visit the Grand Canyon just for the day. We don't want to hire a car but are open to doing something by helicopter, plane or river! I'm really confused from all the talk of west, south rims etc. Can anyone out there recommend to us the best place to go to see something exciting of the canyon to say we've been and seen part of it? Also if anyone can recommend any decent travel companies to use as we don't want to be charged over the top for something we think we'll get which isn't the case. Any help appreciated.
