Returned last Friday from the Fascination. There was no problem with packing 2 bottles of wine in two separate suitcases cushioned in our beach towels we were bringing along. Packed the wine opener in toilet kit, though I don't think there would be a problem in any checked luggage, as I'm sure there's no problem bringing aboard a manicure set, which sometimes even includes an opener.
The room steward was nice enough to keep a bottle iced in our room. It takes away some of the pleasure of having a glass of wine in your stateroom if you must pay around $7 a glass (after gratuity charges are added.)
