I want to visit the Portland area the end of September, but the free airline tickets that I have will only let me fly into Manchester. So I was thinking of renting a car and driving to Portland, does anyone know long this will take and what route I should take to get the best views ? Is there anywhere I should stop along the way, such as Kennybunkport? I will only have four days. I was also wondering how long the ferry is to Nova Scotia?
