I was there this April and absolutely loved it. You got hotel etc sorted? Pasta at la bottega della Gina xxl was amazing, they make it fresh and it’s not a restaurant just a small place with seats outside. We also went to Iris which is fancy but absolutely brilliant. Antica bottega del vino was a class spot too for wine/food. It’s only 15 train to lake Garda which we did a couple of times. Train to desenzano del garda then boat to sirmione was class.
