What time will the doors open for the Elton John concert onMarch 15?

I believe its usually an hour to, an hour and a half.

It is Elton John!! I would check with the arena because it could open a couple hours before the event...

It depends on the event (they differ based off how much of the arena is being used). For Elton John, I would guess 2 hours as I arrived at the PBR an hour and a half before the start and was able to be seated.

Usually 1 hr before events
