I am hoping/planning to be away over Christmas for +/- 2 weeks.

and am making a list of how to fortify my tanks against the house sitter and inevitable disasters.
Aside from a fresh water change, premixed water for top offs, bright red sticky notes warning against over-feedings, timers for lights, equipment checks and rechecks, what else would you do (aside from staying home) to prepare your systems for being away?
Please keep in mind that I do not have high-tech equipment and live in a remote community where the next reefer is 2 hours away. Thanks in advance.
