I put out clothes that are specific to the travel after they are washed and dried, on the guest room bed, any time within a month of the trip. Toiletries are easy as I have a travel supply and bag that I used when traveling weekly for work. All are my own products so I know what I am using. For our Jan cruises I have also added the swim suits and cover up as it will not be used until then. I actually pack the day before travel. We fly to port so I also line the suitcase with a large trash bag and place another over the top of the packed bag to protect in case of rain/snow. Plan personal bag to have under clothes, pajamas, change of clothes and toiletries in the event of an event. We travel carry on size bags so it goes quickly.
