Maybe keep a couple of clean plastic bottles around. You can at least squeeze them to see if they're hardened up before you chill them.
On my very first batch, I'd filled all the available bottles and had like 20 ounces of beer left! So I found an old mason-style jar with a plastic lid and filled it up and stuck some saran wrap over it and screwed on the lid. It didnt carb at all, but I DID feel like grandpa walton sipping on the baldwin sisters' secret recipe. So it was worth it, lol.
