Just did the train from out here in Da Konkoma and have nothing but good things to say.
Ronkonkoma to Elmont/UBS via LIRR direct for game this past Tues. $15 r/t
Empty train and all local stops direct to arena. Tons of space and Isles fans streaming in at every stop. Takes under an hour for me. Brand new station and just allocate 20 min to get to doors of arena walking around the track.
As long as the weather isn't frigid, it's kinda great. Naturally, you need to pay attention to schedule for return trains. Our return trip train came in empty, so no crowding issues. I'm sure trains heading east from Penn will have people on them, but on a weeknight at 10pm, i wouldn't expect them to be that bad.
Bring a hero or something and some beverages and work off those drinks walking to and from arena. I'm down.
