Buy slab-type, slabs kept in a stack to avoid internal convection.
Buy an Al mylar "space blanket" and wrap the slab-stack in many layers.
Best is to store the whole thing in a thick styrofoam box placed inside
a bigger drinks-cooler.
Doing that, you can make 20lbs last for over a week.
While driving, blow outside air or keep windows cracked, so you DON'T DIE.
(Usually this isn't a big issue, since when done right, the offgassing
will be low. People only die when they try using paper bags to transport
many cubic feet of pellet-type, in hot desert environment (with car
sealed, with air conditioning on "recirculate," and with air flowing
through the pellets.)
For Burning Man, I took 30lbs in a DIY chamber made from many layers of
foil-coated 1/2" styrofoam, for walls 6in thick. I was sitting all day
in Center House, handing out chips so people could cool their drinks.
The only problem was with hot wind storms, where my big box was outside
the tent. Tiny tiny air leaks acted like blow-torches, carving little
slots in the surface of my slab-stack. (That's when I started wrapping
the whole thing in reflective mylar.)

Does anyone here have experience transporting and storing dry ice?
If you keep it stored in an ordinary freezer how long will ice cube
sized pieces last?
The closest supplier I can find is a 2.5 hour drive away. Will it even
last 2.5 hours if stored in a cooler or thermos bottle? Would larger
chunks be better?
Thanks.
