The Theatre 29 production of “Mary Poppins” will run Friday, Saturday, and Sundays through March 26. All available online seats for the run have been sold out. To accommodate those not able to get tickets, Theatre 29 has added overflow seating on a first-come, first-serve basis. Patrons wishing to be put in the overflow seating section should be at the box office by 6:30 p.m. for the Friday and Saturday evening performances and 2:00 p.m. for the Sunday matinees. While there is no guarantee a seat will be available, the arrangement adds about another 15 seats per performance. No one has been turned away to date.
