The only real problem here is IF Radisson sticks to their story on the number of formal nights. This would have the greatest impact if they increase(what to wear?) or decrease (causing you to pack more than is needed). On a recent cruise (I was on it) Radisson "threw in" an additional formal night.; and on another they were reported to have subtracted a formal night, according to docs. All any of us can do is to pack according to the docs, and hope Radisson " Straightens up and flies right" on your cruise, instead of making up rules as they go along as they have done a few times in the past.
