I have the same situation and was thinking of the following.
Cover with Solar Cover (to help with evaporation)
Turn off SWCG (to keep chloring from going through the roof while I am away)
Run Main Drains only, not skimmer (just in case comething clogs the skimmer)
I am most concerned with turning off the SWCG, but if I do not, the chlorine will be really high after a week.
Is this a prudent method, or should I do something else? This is my first time going away, and I will be gone for about a week.
Winger -- I'd leave the pump pulling from both the skimmer and MD's That way if the skimmer plugged up it'd just pull from the MD's.
I wouldn't turn the SWCG off. I'd just turn it way down and let it run. If the FC gets a little high you can uncover it and let it burn off after you get back. If you turn it off the FC will possibly go to zero and you'll have to fight that once you get back.
