If I'm understanding what you are asking about....
It's not a pairing, it's a package. A pairing usually involves having multiple glasses of wine during the meal, each glass selected for the course you are having. The package simply provides for a specific number of bottles, and you typically select one each evening (though I suppose you could turn the package into a pairing, since supposedly they will save any unfinished bottles for the next evening).
I cannot remember the exact price, but it seems like it was around $150 for the cheaper of the 2 packages for the 7 day cruise.
I thought it was worth the cost if you want to try some different wines that you might not otherwise try. Certainly it is cheaper than just buying the same wines directly off the wine menu each evening.
Unless of course you are talking about the wine tasting class they have, in which case I'm not sure what that costs.
