One Sunday, June 4 we are taking a guided tour of the Milan Cathedral that ends at 4:00. We have a cooking class that begins at 6:00 located at Via Vincenzo Foppa, 20144 Milano. If we are able to get tickets for the last supper on the official website at 4:45 would we be able to make the cooking class on time? Also, would we be able to travel from the cathedral to the Last Supper to make the 4:45 time slot?
Yes. Viewing the Last Supper has a limited time anyway. Your cooking class looks like it is about 15-20 minutes away (walking) from Santa Maria delle Grazie so you're good. You will most likely be out of the Last Supper by 5:15 giving you a few minutes in the gift shop, which is enough because it's very small too. I would suggest catching a ride share or taxi after your Duomo tour but the Cadorna station isn't too far to walk to Santa Maria delle Grazie. Good luck!
At “The Last Supper” a set number of visitors are put in a holding room to dehumidify them for 15 min while a prior group is in with “The Last Supper” for their 15 minutes. We have seen it twice, such an amazing experience.
