One way or another someone close to you has told you to make sure you pack light for your trip. But it always seems you still always pack a little too much. Since traveling to Europe, I've totally changed my way of packing and feel I've finally accomplished "packing light".
First off, you need to choose luggage that fits your needs but isn't too small for your travels. I would recommend something like an expandable carry on.
Here are a few more tips to make sure your trip is enjoyable:
If you’re not going to wear it more than three times, don’t pack it! Every piece of clothing you bring should match or complement each item or have at least two uses (e.g., sandals double as slippers, a scarf as a shoulder wrap). Make sure your shoes are comfortable and practicle for touring around the country.
Don't be afraid to wash your clothes while you are there. Sinks come in handy and you can get detergent from the store if you are unable to find a laundry mat. If you find yourself needing something on your trip, you can always buy something while you are there.
Don't overload yourself because your vacation should be fun and relaxing and not overwhelming!
