Im from canada and here 90% of arena shows have chairs on the floor and thats what i prefer
-No need to stand in line all day to get a good spot
-No pushing no shoving
-You can sit down during the often boring opening act
-You can go to restroom, bar, restaurant,t shirt stand without losing your spot
-You can sit in the hour before the show,
during the long intermission between acts
Once the headliner starts you can just fold the chair and stand
