Packing for vacations can be time-consuming and such an exhausting task. Us, Beach Junkies have a customized packing list that we created four or five years ago and it makes packing simple. Probably about two weeks before our trip, we start putting away clothes that we want to take. If we are traveling in the summer, we put clothes aside so we won't wear them and have to launder before our departure. If it's winter, we pull out those summer clothes that have been tucked away for the season. I think the toughest part is figuring out what to bring. In terms of clothing, the easiest thing is to do is choose a colour scheme and bring clothes that have a dual purpose (scarf/sarong or cover up/evening dress). Once you have figured out what you are bringing, packing everything in your luggage is a piece of cake. Check out this method:
I have started this style of packing a year ago. I just considered it "rolling up my clothes so it fits nicely in my luggage" but a couple of months ago, I came across a blog who called it the Burrito Method of Packing. So instead of piling up all your clothes in two separate piles, you simply roll up all your clothes and arrange it nicely in your luggage. You can definitely fit more in your luggage and nothing gets wrinkled.
