My royals usually prefer the cool side (26c) to the warm side (32c) - even with identical hides. But it's a good idea to experiment with changing the hides around, to see if she has a favourite. (If she does, you will have to buy her another one of the same sort to put in the hot end...)
I had Tig's temp at 93 to boost his metabolizm, but he wasn't liking it and stayed in his cool hide. I reduced it back down to 90 (what it should be at) and now he stays in the hot hide.
Try reducing it down to ninty, that's where it should be at.
