Why take a chance? I would turn water off but leave all faucets and valves open. A little RV antifreeze in the toilets and you're good to go.
If there is any residual water in the pipes, they're not likely to burst with all the valves open.
When I've done this in the past we just come in, turn on the water and then close all faucets and valves one by one to clear them.
