Retirement Trip Campground Recommendations

I think it is a great opportunity to spend time and make some great memories with your family. I can only suggest that you might want to stretch it a bit further because that is quite a trip and there are tons of things in these places to see. I try to figure a 'rain day' or an 'I'm tired of driving' day to rest my eyes and replenish my sanity occasionally.
Take lots of photos and label them as you go because you will forget each individual shot as time passes.
