We have made reservations for coming back home from NYC on a Sunday (Memorial Weekend). The train does not leave until 3:45. Our thought is to bring our suitcases and check them in. We will be coming off a cruise so we will be there fairly early in the morning. Now the big question. Is there anything with walking distance to do around Penn Station? We don't want to count on taxis or the subway (have taken the wrong one and went the wrong direction last time). Any ideas?
