We will have two days to see Lake Garda. We are staying at Desenzano and will spend one day at Sirmione. What would be the best way to spend the second day? I am disabled and can't walk far. Normally when we visit a place we take the sight-seeing buses which allows me to sit and take in the sights without tiring me out.Is there anything we can do similar to this in a pretty place that you could recommend? Thanks.
