Hi, we are travelling to the States in April 2014. While in Las Vegas I want to do a day trip to the Grand Canyon. I am travelling with 3 kids 10, 8 and 6. I know its a fair distance away from Vegas so could anyone suggest the best type of tour with kids? I was thinking the all day bus trip as its the cheapest for five of us, but I'm not sure my kids will handle that long travelling after arriving a few days prior from Australia. We unfortunately only have time to do a day trip not stay over night. I really want to take my husband and the kids to see the Canyon while we are there. Thanks for your help.
