Okay so everyone told me Milan is a 1 night stop, just see the Duomo and move on. But I booked 2 nights there before Lake Como and now I’m second guessing. Beyond the Duomo and Galleria, is there enough to fill a second day? I’ve heard Navigli is cool for aperitivo, and there’s the Brera district? Last Supper is sold out for my dates already (of course). Would love to hear from people who actually liked Milan.
