The prices for the Wine and Dine package are on the RCI website under Gifts and Gear section. 3 categories withe same wines in each and then one or 2 more. Very limited and not worth it IMHO - buy off the regular wine list - photos of which is here so you can see the selection and prices. http://community.webshots.com/album/562747533yjShXM.
These prices are from memory 3 pack $79 5 pack $109 7 pack $129 all +15% Grat & IMO are hardly worth it. Choice is limited & unless your preferred wine happens to be the most expensive in the pack, the saving is barely worth the bother. Best deal on RCI is probably Portofino's Restaurant at $20 Inc tip (a little over a tenner).
