I've bookmarked this picture so I can find it easier.
That's my Intex pool last winter here in southern Wisconsin. I drained water below my inlets, removed all hoses and valves and put those inside along with the pump and filter. If a sand filter that can really stay outside if drained, valve in winter position and covered. Otherwise bring it in.
The main issue I see with your pool is it looks a little shorter and the inlets appear to be about 1/2 way down the pool. I think draining the pool over half way would be a little much. I drained about 1/4, or maybe 1/3 to get below my inlets. One thing though with my skimmer is I no longer use those inlets, and because I kept all the stuff that came with my Intex I discovered they include two black plugs that can actually plug the inlets from the inside. I think with your pool if left up you'd want to plug the inlets so you can remove the hoses but not drain the pool over half way, which I feel would leave it a bit unstable. Perhaps someone who has a shorter Intex pool could chime in if that's the case or what they do.
