We have reservations at to see the Last Supper in March. The reservation is for the time 13:00 for 15 minutes. In your experience are they on time? We would like to catch a train at 14:05 from the main train station - Is this reasonable?
Jim, I saw the LAST SUPPER in December and they are most certainly on time . . . both entering and exiting. There is a metro stop nearby (Conciliazione - red line) and you'll need to transfer to the green or yellow line to get to the main train station. The link for the Milan metro is here: http://www.atm-mi.it/ATM/eng/Muoversi/Pianta_trasporti/
Jim ~ I was there last summer & even during the crowded summer they are very punctual. As Kim stated there is a metro stop right there. Good luck & enjoy
