I too would highly recommend calling the box office directly....when I go on road trips I usually take my dad who can't really do the stairs and is handicapped. Every arena we have gone to it takes a phone call and they have sold us two accessible seating tickets or exchanged our tickets for accessible spaces....which in reality usually turns out better as the accessible seats are always at the top of the bowl and usually excellent sight lines to watch hockey. This has even got us face value tickets to sold out games such as at marriucci,...again credit goes out to the marriucci staff who really did a great job in making the experience easily accessible for him.
I would call.
