We are a family of four planning a two week RV trip in the US this summer. Our kids are 11 and 8 and have never been to the states so we would like to show them some spectacular scenery and a bit of legendary America. The only sure thing we know is that we want to take them to the Grand Canyon. My husband and I have already been to Bryce and Zion so we wanted to try different national parks this time round. I was hoping that this forum could help me plan a trip that doesn't involve long road journeys every day and that will give the kids the chance to get outdoors in great national parks and good campgrounds. I don't know if Yosemite is too far away to contemplate. Any help in sketching out an itinerary would be much appreciated.
