For Feb. cruising, do bring one outfit for "cold" weather. We've done at least 7 cruises in Jan/Feb as well as multiple trips to WDW. Most were great, but on 2 trips it got much colder than I expected and I spent a small fortune buying warm clothes for DD.
FOr "normal" weather, shorts will be fine, but you will want a sweater or jacket for evenings.

What excellent costumes! I especially like the picture of kids being kids
