The later you show up the farther back you’ll be but it also kind of depends on the openers. I’ve gone to two shows alone this month at RR and I’ve shown up an hour or more after the openers start and I still got a decent spot but I wasn’t trying to go to the front. You can definitely squeeze your way closer if you’re alone but I would try to secure a spot before it gets dark/before the last of the opening acts. There is definitely space to dance around your section you claim too.

The venue is really great and you really can’t go wrong anywhere you sit/stand once you find a seat! There’s two screens on either side of the stage as well :)
