I got 10th row, Christine-side, despite being a day late to the pre-sale due to travel snafus. It doesn't appear that they're doing meet 'n greet/VIP, but the tickets are plenty expensive regardless
About the acoustic guitar mystery: you make a valid point Rudie of course that it's reasonable to assume it's Lindsey. The only thing holding me back is that Lindsey has such a distinct tone/feel to his playing that one usually doesn't have to wonder, "Is that Lindsey Buckingham?"; you just know it's him. His acoustic playing has a very distinctive percussive sound and even his electric guitar (thinking of the chord flourishes on Bob Welch's "Sentimental Lady") is hard to miss.
