I'd wrap your electric water heater and just keep it on. Given how little water you're using, I just don't see it making much difference turning it on for an hour to bring it up to temp from whatever it falls to the other 23 hours and keeping it at one temp—essentially, like the equation of keeping a house at one temp vs. dropping it and having to catch up later. The only difference is that a well-insulated water heater will lose very little heat.

Yes, I agree about wrapping the tank. That's on my list also. I will need to compare leaving it on 24 hours and 1 hour. My last electric bill was just $55. I'm sure turning off the water heater is a large part of that low bill.
