Personally, I'd rather pony up the extra cash instead of standing in line for hours...but that's probably due to my lack of patience.
A couple of friends of mine just got back from Vegas and they paid $200 each for VIP passes to Donny and Marie's show
At first, I thought they were kinda nuts to pay that much money for a M & G with Donny and Marie. But after listening to them talk about their M & G, they obviously enjoyed every second and would gladly pay to do it all over again!
Some folks are obviously not going to be into paying for meet and greets, but at least the option is there for those that want it. I'd like to see Luxor/Cirque do these M & G's on a more regular basis...say once a month instead of once a year? That would be cool!
