Some in the case of Donna Vekic did so from an airplane; likely on her way to the Australian swing and to start her new season; but it still didn't stop her toasting in the New Year.

Petra Kvitova on the other hand took time out to practice before getting on with the night's events; with her wondering if she can stay up till Midnight.
