I was wondering today if Cinder infiltrating the CCT during the dance had other reasons besides supposedly making it easier for her to sneak in. Sure, that didn't work out very well, since Ruby easilly spotted her, but it kinda makes sense that she would think that. But I think the reason why she wanted to do this during the party was a combination of a few other reasons:

1) with everyone distracted with the dance, not only would it be easier for her to go by "unnoticed", but it would be easier for Mercury and Emerald to keep an eye on any potential threats - both the teachers and possibly the students on her list. They're only 2 people, it would be impossible to track the other's movements when they're all scattered, and if they just kept watching the CCT entrance, there is a possibility they wouldn't be able to do anything to stop anyone without risking Cinder being discovered

2) She probably thought blending in with the other party guests would be a faster way of losing any pursuers than, say, running to some hideout. Even with the security cameras, it could be a bit hard to find her there, and even if one of the dancers noticed her getting in, they'd just assume she arrived late. I also think there's a chance that whatever it is she uploaded to the computers probably took care of any security footage for her, assuming she actually thought about those. Either that, or hiding one's cheekbones really does make one unrecognizable
