Any reason not to just shut off the hot tub? This lowers the temperature to ambient and also disables the ozonator.
Would this cause problems with heater corrosion as the temperature falls, or does chlorine need additional mixing?

You are correct. Ozone reacts with chlorine so if you have a way to disconnect the ozonator (say by turning off the UV or CD device) then that will help make the chlorine last longer. An ozonator can be helpful in a high bather-load situation such as a residential spa used every day or two, but isn't so good when there is no bather load because it just increases chlorine demand.
