I'd like to add that this is worth doing, even if you're not a "wine person"...just b/c it is so informative. Also, it's worth doing if you've done it before. We did it on the Magic 2 years ago, and the WOnder last year. Each sommelier (my spelling stinks!) gets to pick the wine, and even if you, for some reason, get the same people twice (a team does the presentation, with the head sommelier leading), there is a good chance that they will not pick the same wines twice. So, it's never the same presentation twice. THe only thing that is standard, I think, is the champagne, which happens to be mine and DH's favorite anyway, so that's not a problem with us!
5 glasses of wine, 1 glass of champagne, bread, grapes, cheese, a pin, and an hours worth of knowledge for $12....a great deal!
