My thanks for earlier input. I have an updated approach. I understand there are a couple of long train trips here but think it's a better route for our family given our desire to see a range of places. Train travel is the plan with the exception of the flight from Venice back to London. Any critical flaws here given we are willing to spend some time getting to and from various places and seeking some city time balanced with more bucolic? Thanks!
