Can I make a 5:17 train (Penn Station) after The Sound Inside Sunday?

Seeing a Sunday matinee and was curious if it is running quickly enough for us to get to Penn Station? Next train isn’t for another 3 hours so want to try to make the 5:17. 

I already have tickets to the late change but can exchange them if we see we make it, just curious if I should bring my backpack with us and try or leave it back at the hotel to collect later (after a long dinner I guess),

I was also at the October 6 Sunday matinee.  I was at the parking lot getting my car about two blocks from the theater at 4:40.  I think your biggest logistical concern is getting from Studio 54 to your platform at Penn Station platform in 45 minutes or less.

my reaction to this is, "why stress yourself?" 

you say you already have tickets for the later train.  i would just enjoy the show, take your time getting out, take your time getting down Penn Station, hang out at the food court, and then catch your train.
