I am a big believer in traveling light on international trips and you will find a wealth of information on ways to pack. I am a fan of this web site: http://www.onebagtravel.com. On the web site and with the accompanying video, this site provides information on packing and packing well. In addition, the information provided on travel is invaluable and is a great resource.
In addition to this site, I also use this site: http://frugalfirstclasstravel.com/2013/04/13/real-life-one-bag-travel-my-packing-list-for-spring-in-europe/. Packing effectively for travel is a BIG deal when you have to carry bags and such on planes, trains, and in vans etc. generally speaking, if it is small, it CAN be easy.
Soooo….take a look at these sites and let me know what you think!
