how early for barricade

This is premature but i have no been to a concert where i needed to be there for a good spot in years. Im going to nashville and have VIP what time should i get there to get a good number wristband. I wanna get a really good spot on barricade because i need this experience to go well bc im stepping so far out of my comfort zone going alone and traveling for the show!! lol i just wanna make the most of it! So how early to get like single digit wrist band number?!
