Kids' Night on Broadway lets you get FREE tickets to some of Broadway's best shows for any child aged 6-18 accompanied by a full-price adult. It takes place in New York City February 25-March 3, 2013 - and tickets are on sale now.
See the entire list of Broadway and Off-Broadway shows at the Kids' Night on Broadway site.
On Kids' Night, parents can also get other deals, like area restaurants where kids eat free - generally, restaurants offer a free entrée for each child accompanied by an adult who purchase a regularly priced entrée, but check the details - pre-theater parties, discounted parking and more.
Here's more information from New York Show Tickets.
Kids Night on Broadway is about more than just visiting the Broadway theater. The Kids Night folks do their best to really make a night of it by throwing pre-show parties, holding music/dance workshops and discussions with Broadway writers/performers, and offering discounts at restaurants in the theater district. Times Square area restaurants ... often participate by serving a free entree to a child who is accompanied by a paying adult.
Also check the Kids Night on Broadway website for additional special offers, which include discounts on local attractions like Madame Tussauds. Other perks include a special Kids Night on Broadway Playbill for the show you're seeing, and parking discounts for those who are driving into New York City.
Parents should be aware that some of the participating shows are too mature for kids, and some are maybe even a bit mature for teens. So don't assume that because a Broadway show is on the Kids Night list that it is age appropriate. The event's website has a "Note to Parents" section for most shows which gives a rundown of any objectionable material, but you may also want to do a little of your own research.
