Total newbie here to European travel. Have always wanted to travel to northern Italy to see where my acestors are from (Lake Como area). Any recommendations would be appreciated (ie time of year to go, where to fly into, how to get around, where to stay, side trips). We will be traveling with pre-teen kids. We r not into the touristy scene. Would just like to relax and immerse ourselves in Italian life. Possible side trip up into Switzerland?
