If you bought multiple passes in a single transaction, you will be able to book as many tickets for each attraction as the number of purchased passes. If you mistakenly select only one ticket, you should still be able to select that same attraction in the “Activities” section of your app and add the missing tickets to the same time slot. If you are unable to add more tickets to a certain museum, please contact us through our form or send us an email at support@milanocitypass.com.
