Theatre 29 has added some seats to their sold out production. Managing editor Tami Rolloff has more… In a remarkable phenomenon, “Disney’s Little Mermaid” sold out all available online seats prior to its opening March 11. Overflow seating has been added on a first-come, first-served basis for its performances tonight and for Sunday’s matinee. For those willing to take a chance, arrive at the theater box office about a half hour before curtain, 6:30 p.m. tonight or 2 p.m. for the Sunday matinee. You will be placed on overflow seating list in order of arrival. While there is no guarantee a seat will be available, this arrangement will add about 20 additional seats per performance. Tickets are $15 for regular admission, $12 for seniors and military, and $8 for children under twelve and students with ID.
