We are a retired couple planning a road trip by car from PA to the Grand Canyon. Our trip would take place next year around july august period. We have no problems getting around physically, so some activities along the way would be great. Looking for suggestions for places to visit & decent places for over night stays. Time is not a problem. Can anyone suggest things to do at the Grand Canyon besides viewing. Maybe a great hotel stop for a few nights. We may also continue the trip to California then head back through Arizona. Any suggestions would be great!
