Santa Claus may be coming to town, but you'll need a reservation to see him.

The Macy’s flagship store in New York City began taking reservations Monday for a chance to sit on Santa’s lap while visiting Macy’s Santaland.

Families can go online to sign up for a time slot from 30 minutes to five days in advance. Admission is free to Santaland Herald Square. Professional photo packages start at $20.99.

Macy's says the system was designed to cut down on wait times that got very long, especially during the busiest days leading up to Christmas. 

The department store says families can cancel a reservation and make a new one at any time. And they say don't be too early or late for the time slot.

Reservations can be made at the Macy's website.
