6. Roll, don't fold, when you pack, and unpack right when you get there. This is a trick I learned years ago and it makes SUCH a difference. You can fit more, clothes don't get so wrinkled, and you can layer the stuff you know you'll wear first on top of the stuff that is less important. Unpacking and hanging stuff up saves time on ironing and digging through your suitcase each day. Here are some photos of that process from past trips.
I'll be sure to share more photos & tips in the future. Any specific questions? Would love to hear your packing struggles or thoughts - definitely something I have more than enough experience with!
