Yeah, if you have a cover, and can maintain the water while you're there, and cover it while you're gone, that would be a practical solution, I think. Pretty low maintenance, too.

Just don't make the mistake of forgetting to chlorinate fully when you arrive, and then trying to 'catch up' right before you leave. When chlorine burns up goo (mostly, people goo), it produces intermediate compounds that are broken down by chlorine + sun. If wait, and dose right before you leave, those some of those intermediate compounds will go to forms volatile halogen gas forms, accumulate under your cover, damage it, and then stink like crazy when you pull the cover off.

So, add your big chlorine doses when you arrive, and not when you leave.
