Don't blindly trust the promoters' description - VIP is often just a buzzword without any real added value. Some offers are just pricier tickets with a standard merch bag that you can skip. Before you pay, you need to find out if it's actually about better sightlines, early entry, or something genuinely special like sound check access.
The practical hack: Send the promoter's email address or concert account a question about what exactly is in the VIP tickets. A lot of them respond pretty thoroughly when you ask specifically instead of just reading the vague website text. It's also worth googling past concerts by the band - see if people wrote anything positive about their VIP experience afterward. That's way more telling than the description itself.
If it's about seating (better view, closer to the stage), that's usually always worth it. You're paying for a better experience, not for gimmicks. Meet & greet packages are more of a gamble - it depends on whether the band has time for everyone or if it's just a quick second. The double cost is pretty harsh, so I'd skip a standard seat upgrade and instead try to lock in a good spot early without the VIP label.
