Once you open all the faucets (hot and cold) and turn off the pump, the water heater will drain.
However, the plug, I believe is lower in the tank than the cold water inlet.

Any particular reason for draining the system between trips? Because once you open the water system to atmosphere, you will HAVE to re-sanitize and refill for every trip.
