My theory is she was having one last 'girls night out' weekend with Yang, who was heading off to Beacon soon.

And the reason why Yang wasn't there is because she was off chasing leads - they probably spent all day together, so Ruby would be understanding of Yang wanting some time to herself to go hang out with her friends, and is probably used to Yang going off on her own to do stuff.
