A very good idea. I've done three USA holidays and would like to do another, but have hit a problem.
I have a strong dislike of long distance coach travel, but realise quite a lot is necessary on USA holidays. However the distances involved and percentage of holiday time spent on a coach makes me reluctant to book.
I was close to booking The Historic East Trail until I realised that the coach travel includes one day of 325 miles.
If I'm using the web distance calculator correctly the Heart and Soul holiday has a 395 miles day, which for me is out of the question.
A two centre holiday with air travel (or perhaps even rail) between them using each centre as a hub to explore that area would be ideal.
