Modify reservation made with companion coupon
 

I am going on a cruise out of Manhattan and want to use the companion coupon to get a roundtrip from Hartford to NYP in February for my fiance and I. The way down is no problem but the way back is proving to be difficult. I want to take the 11:33am Vermonter direct to Hartford but not sure if I'll make the train as i have to get off the ship and go through customs which should be fast but you never know.
I want to know if it is possible to change my train to a later one the day of if I can't make it in time. I know I can get a 3:30pm train but it would mean sitting in NYC for a few hours and its not direct to Hartford.
I also would rather not transfer to a shuttle unless I have to.

The transfer is extremely smooth at New Haven and guaranteed, hundreds of people do it every day, I would consider booking the connecting train and taking your time off the cruise ship. Last time I got off a cruise ship it took a while for them to let everyone off.
