Leaving RV anti-freeze in the grey / black tanks for a week?

Thinking of just de-winterizing our camper at the end of our drive this season and I don't want to just dump the anti-freeze from the lines in the street, and I don't feel like trying to hoist our honey-bucket into the house to run it down the toilet.

Is there any issue (other than weight and sloshing) to leaving the water / rv anti-freeze combo in our grey and black tanks for a week, until we go camping next weekend and swing through the dump station?  There'll also probably be a few gallons of sanitizing solution (bleach + water) in the tanks as well.

    RV antifreeze is "generally recognized as safe" propylene glycol.  If it was safe enough to sit in your pipes and water tank over the winter, it is certainly ok for a couple of weeks in the gray/black tanks.
