As long as you are aware that it may not be warm and sunny then there should be no reason why you wouldn't enjoy going. Restaurants, bars, hotels and attractions are generally fully open by Easter, just be prepared for all types of weather. Torri del Benaco is one of the smaller towns on the lake but if you are travelling by car you would be able to get around easily from there. Ferry services will be on their shortened Spring timetables and services to and from Torri are very limited.
Thank you! We enjoy traveling when it's not so crowded so this sounds perfect.
