Check with tour desk or concierge when you board. I seem to remember that some of the Norfolk boarding passengers were at theater when we embarked. I can't remember from whom I heard this. With a 2:00 pm start, most shows are too long to take a chance on a non-Radisson booked excursion although "Movin' Out" and "Little Shop of Horrors" come in at around two hours. That would give you plenty of time to get back to the ship. One of the New Yorkers can correct me but I think it would be faster to walk back from the theater district than to take a cab since a cab needs to go to 55th (IIRC) to get on ramp to pier while walkers can go against traffic.
