After a bit most folks have a pretty good idea of how their pool acts over a week and what it needs, i.e. acid, chlorine, etc. I lower pH to 7.2 or so and raise to shock level for anything over a 3-4 days. Less than that, I would recommend a couple of pucks. And run the pool as normal in any circumstance.
The other concern is debris...if you have an environment with a lot of leaves you will need help from family or neighbors to empty skimmers or switch all suction to the main drain to ensure pump gets water.
Some of the best options are automated chlorine; whether it is a SWG, Stenner, or a neighbor up for daily dumps or pre-measured chlorine from leftover bottles. This most closely replicates your normal care and keeps things in check. Downside is none of them are actually testing the pool, so it's important to have an idea of your pool's typical demand.
