I wasn't trying to take a dig at Maiden for them not doing meet and greets. We're in an age where if you're a musician and the ability to live off album and ticket sales isn't altogether feasible anymore. SOOOO many bands do VIP meet and greet upgrades to survive. Maiden could offer that, but they offer First to the Barrier instead. Again, it's their prerogative and they deserve to have 100% say as to how they spend their time before shows. A very likely possibility is that the reason they don't do VIP upgrades is to manage the size of crowds who would pay for that experience. Likely, they'd have to price it ridiculously high like KISS (which were what...$1200 on the tour BEFORE End of the Road, and now they're probably up in the $5K-$7K range?), and they don't want to price gouge their fans like KISS does.
None of what I've said is meant to imply they don't care about their fans. Even on the recent tours, I don't think I've heard a single instance where they're spotted on the street, in a hotel lobby or bar and they're not happy to take pictures with fans. It apparently happened when they hit a local bar near the venue they played at my stop on the LotB tour. And just like Blaze, that's for free, with Maiden it's just unscheduled and based on purely on luck.
And just in case it doesn't come across in text, I don't mean to sound argumentative, just clarifying my comment and along the way you've made me think of a more likely reason for them not doing VIP in the process.
