We have been to Helsinki before -- so we would like to visit Porvoo -- since my husband has some mobility issues -- I want the trip to be as easy as possible. I was thinking of a guide with car to meet us at pier and take us there, show us around, and then return us to the ship. Are there better ways to do it? How can I find a reliable guide? Where should we eat in Porvoo -- some place that is not overrun with tourists but convenient and good? Thank you.
