Kay,
One advantage to living up north is the fact that many people are lucky enough to have basements. That's where I store my Harbour Light boxes. Unfortunately that's not the case in Florida. When I lived in Texas I had a spare bedroom that had no bed - just boxes.
You could always:
1. Purchase a larger condo.
2. Rent a small storage facility.
3. Knock a hole in the wall and use your neighbor's space.
Trashing the styrofoam packing is not the end of the world.
