This is a free event, which are very popular and attract crowds. If a museum nears visitor capacity, the staff at that museum may implement timed tickets at the door on a first-come, first-served basis to better serve guests. No advanced tickets will be distributed. Should there be wait time for entry, visitors can check out holiday-themed activities taking place at Merry Main Street - another City of Mesa family-friendly event - and 2nd Friday Night Out in Downtown Mesa. Both events are within walking distance from the museums, along Main Street. Enjoy food trucks, a Christmas market, an ice rink and more.
