Feel free to book your tour as soon as it becomes available for sale. Our calendars are open up to 18 months, allowing you to secure your spot whenever you feel prepared. Early sign-ups are appreciated as they assist us in planning our schedules. If you’re planning a museum visit with a party of 6 or more, it’s advisable to sign up in advance. Please note that in most museums, larger groups (6+) may need to be divided, as tours are typically limited to 6 guests per guide. Signing up earlier ensures that we can better accommodate your party’s needs.
