I have sent quite a bit of cotton candy over the past few years. One package was a circus theme with cotton candy, circus peanuts candy (those weird spongy orange peanuts - my Dad likes em), peanuts in the shell, drink mix packets, clown noses, yo-yo's, juggling balls, a rubber chicken, and a little stuffed elephant.
The dried ice cream is good. Most of the freeze dried meals I've had camping and backpacking were not something I'd send. ha! But the ice cream was good.
It is getting warm there, so just send it out quickly and hope for the best! Or if you are really concerned just send something else that you know wont risk condensation.
btw, are you really a square dancer?
