Thank you for the ear to ear grin today. How do I go on one backpack? A willingness to do laundry and bring clothing that can double from day into night. For example, I have a black skort that easily can be used for a daytime excursion with a tee shirt and sneakers. Take that same skort, pair it with a dressy blouse, evening sandals and voila, a night time outfit. In general, most of my stuff can double from day into night depending on the accessories. Also, I roll my clothes so it takes less space. Furthermore, I make a list of must have and likes. If the likes do not make it, so be it. But, the biggest thing is the willingness to do laundry. I am taking the train from Chicago to LA and before I get on the plane for Papeete, I will do a load. I plan on using the service onboard. I absolutely hate carting around lots of bags and if I buy anything that can be shipped, I do that, too.
So, lay out what you think you want to take, and compare the size of the bag. Begin the cull that way. Also, you will find half the stuff you thought you need you do not need at all.
By the way, which cruise? I am on the August 17th sailing.
