Have to say I've bought the wine packages several times to avoid the hassle or maybe we didn't drive to the port & I didn't want to weigh down luggage, etc.
...but...the choices aren't all that great, if you like good wine-- pretty much have to go for the premium package & still pick & choose at that.
AND if you don't finish your package they load you up on the last night with the extra bottles so keep that in mind if you're flying back - can't even put unopened bottles in your carry-on anymore...
so better to drink it up if you get the package: take the bottle back to your stateroom to finish, have them bring you a bottle at lunch if you want in the main restaurant, order champagne at Palo, etc.
