I just got mine yesterday, but she seems to be the same
Late last night she finally decided to curl up into her cool side hide, but at that point the hot side was only about 86-87 (I don't have a probe on the cold side. I've got a thermometer, but I can't really measure it while she's in there) So I have to imagine the cold side is only 78ish (the ambient temp now is about 78, but it was low 80s all yesterday when she was crawling all over, sticking her nose up towards the edges of the lid to see if there was anywhere to get out)

But then, it's all brand new to her, so maybe she's just checking everything out.
