r/AllegiantStadium

I've never been to a BTS concert (or any concert). I bought tickets to one of the back rows in Allegiant Stadium (row 11). I wanted to ask folks out there who have been to these concerts previously:

1. It looks like assigned seating? Is it?
2. Is it enough to arrive half an hour before the concert or do I need to be there way earlier?

Coming to a football game in October and will be looking for an Airbnb nearby. Any recommended areas of town with nit to far of an Uber ride to the stadium or areas to avoid? Thanks in advance!
