I try not to worry TOO much when I don't see my snake in different hides because I have to presume they are moving during the night when I am asleep. As long as the temps are regulated and are reading within desired levels, you should be fine. With the humid hide it does add an extra bit of concern though because you don't want scale rot etc to become a potential issue. How do you have the humid hide set up?
If your humidity is that high in the cage, I personally don't really think you need a humid hide. If your humidity was 50% or something I would say go for it. But if it's consistently 70% in the cage that's already on the high side.
