Look over this site and your program guide and plan your day before you begin your activities. It's impossible to see everything, so pick two or three indoor performances and plan back-up options.
Most events begin at scheduled times and venues are cleared between performances.
There is no reserved seating. Late admission is rare and at the discretion of each site's management. Make sure to allow ample time to travel from one location to the next. First Night events usually attract full houses, and locations close to Copley Square and Boston Common tend to fill up quickly. Don't be afraid to venture off the beaten path because the performance you see by chance just might be your favorite.
