We almost always start packing about 30+ days in advance ... though mostly the little items needed ONLY for a cruise ... items not needed at home. That being said, we lay out out clothes about 2 weeks in advance. Rolling clothes is best at keeps clothes wrinkle-free. On the other hand, if you find something is really wrinkled, there is onboard laundry (including a free iron) OR ... you can have a garment PRESSED for about the same price as a local, land based cleaners (typically, about 1/2 the cost of having the item cleaned and pressed). With that in mind ... we have had NO issues with packing for the past 13 years of cruising. Only ONCE, did we ever have to get my tux pressed ... and that was only because I folded it several times into a Pullman (luggage), instead of using a garment bag. Most everything else is fine.
