I am going with Shearings to Lake Como the last week in March 2012 and am unsure what the temperature will be like at this time. Should I take plenty of warm clothes for the day and night or will it just be chilly on an evening? I will be going on my own. What sort of places will be easy to get to (using publis transport) once I am there? Usually extra trips are offered once you arrive. Are any of them worth paying extra for?
