Packing is so complicated for me. I love the cubes for warm weather clothes. I roll the tanks and use the big one for the shorts so I don't have to fold them. I don't like cubes for long pants and sweatshirts, these work better rolling or folding normally and not shoving them in a cube. I can't get it to work and I had most everything packed in one before France last year and then re did it all when it wouldn't fit right with the cubes. I don't feel like I need more/different sized cubes because what I have works great for WDW or warm weather trips but I also use the bigger suitcase for WDW because of
MDE etc. The cubes just don't work in my smaller suitcase and smaller cubes wouldn't help because the clothes are bulkier. I def see the advantage but not for everything. And if I don't use them I do a combo of folding and rolling so I'm nothing if not inconsistent
But I also don't find the cubes or rolling stuff gives me any more room than just folding them does. I think it's all perception to sell more cubes
I do like cubes and bags to contain small things, stuff I don't want getting pawed through when my suitcase is opened and shoes. I like the fun disney or other design drawstring bags Target sometimes has in the dollar spot, though I think the bags are generally 3 bucks now.
But I also either label outfits or take photo's of them so I know what to wear on each day, especially at WDW since I take the same shorts. Need to make sure I'm not wearing the same thing to meet a character that I've already worn before.
