The shuttle bus is easy enough, have used it for the three games I have been there, both travelling solo and in a group, never had any issues either before or after the games. Its an easy 45 min train ride from the city and you can get the tailgate started on the train. The only part that can suck is the wait for the train back but then you can always hit up a local bar or the famous grease wagons are literally a 5 min walk from the station
