Other option - look into no-chill brewing. Basically put the boiling wort into a food-grade plastic container, squeeze out all the air, and leave it at room temperature. Only one caveat, and it's really important...
YOU HAVE TO USE IT WITHIN FOUR DAYS!!!
Boiling does not kill botulism spores, and their incubation period is 4 days. This is serious stuff, people die from botulism. But if you only need a couple days, you can do this safely.
Again, USE IT WITHIN FOUR DAYS!
