You could always just store the clothes in your suitcases until you're ready to actually pack for the trip. Personally, the OCD in me prefers to wash the clothes one more time just before packing so that they all smell super fresh and clean for the trip.
We do a combination of most of the tips above. I have a dresser dedicated to just travel stuff (two drawers just for cruises, two drawers for general travel gear, and one drawer for miscellaneous items and paperwork). I also have a couple of large totes that are dedicated to whatever the next big trips are so that everything ends up in one place for when I'm ready to start packing. We also have a section in our closet for favorite travel clothes. I make a calendar that includes each day of the cruise, plus travel days to and from ports. Each calendar square has the date, where we'll be that day, and any extra events (Formal night, Semi-formal night, Palo, Spa, Frozen night, Tangled, night, Pirate night, excursions, etc.). I write in what we plan to wear each of those days as we pack (DH is notorious for never packing enough so this is the best way to ensure he's good for the whole trip!). As for packing early... for our bigger trips, I like to have everything packed and ready to go at least one week prior to leaving. For shorter trips, I like everything done at least 3 days before. This way, we can relax on the days leading up to the trip, starting it well-rested and stress-free!
