A week or so before the trip I put clothes aside on hangars for the trip. I also check over the toiletries bag ( I use an old fashioned toothbrush on trips - so none of this needing to put things in the day of the trip except for maybe a bottle of foundation). Night before I lift the hangars off the rod, fold the clothes (hangars and all) into thirds and lay them in the suitcase. Fill in empty areas with shoes, toiletries. Get to the hotel you lift them up and out, hang them up and you are ready to go.

Remember: Less is more. Send some items out to laundry if need be. Lists definitely help but fulfill those lists throughout the week, putting the items in a dedicated space or the suitcase.
