I have a ticket from Penn Station (NY) to Trenton on the NEC. I'm new to the city, and work next to WTC. I was thinking of taking the PATH to Newark-Penn and picking up the NEC there.

Would I have a problem with my ticket since it says from NY-Penn station, even though I'm basically just getting on the train later?

This is for a trip tonight, so I'd appreciate an answer ASAP. Thanks.
