Yes, agree with your statement, it's tough but not brutal and people should not be put off. It is a long distance trail that can be done over as many days as one wishes, be it 4 or 20+,camping or B&b, using a baggage transfer company or not, doing it in one go or several trips. There is no right or wrong way and I believe that it's achievable as long as you are reasonably fit and train appropriately for it.
