Through rain, sleet or snow may be the credo of the U.S. postal service, but it applies to Broadway as well, where the show must always go on. Despite heavy snowfall and even blizzard-like conditions in New York City overnight on Saturday, Broadway shows are still running as usual. Fortunately the snow didn’t get heavy until after curtain last night, and it had ceased by morning, meaning that Sunday matinee-goers won’t have to brave a flurry of flakes. Of course, the accumulation on the ground is another story, so anybody traveling more than a few blocks to Times Square may want to give themselves plenty of time to get to their theater. For people outside the city who can’t get out of their driveway and want to cancel their tickets, they can try calling Ticketmaster or Telecharge to see if they would be willing to exchange the tickets for another date. However, please be aware that technically both of those services have a ‘no refunds or exchanges’ policy.
