Hopefully these babies are going to teach me to be a more efficient packer so we can travel in carry-ons. Someone posted about them on a thread I had started about using space bags - they said they used the Eagle Creek Packing Cubes... I just ordered the eBags brand 'cuz they were cheaper than the Eagle Creek ones. I am going to try rolling my clothes when I pack rather than folding & making stacks. I plan to use 2 larges per person - one for tops & one for bottoms. Then I can just take the cubes out of our bags, fold back the lids and set them into the drawers. Depending on which carry-on bag I'm dealing with I can fit 2 larges + a medium or 2 smalls + a couple pr. of shoes/sandals.
The ones I ordered came already so I started playing around with them a little bit just to see what I could do with them. I found that I can get about 12 of DH's T-shirts in a large cube and with my stuff I got 3 pr. of capris & 8 pr. of shorts in one!! I was able to get 10 of my summer tank tops / T-shirts in a medium size!!

Now of course if we were to travel in winter they wouldn't hold as much stuff as winter clothes are heavier & bulkier. (I am going to bring some of the space bags for the dirty laundry.) I think overall, packing for FL weather is going to ROCK now!!
