Savi's as a walk up during Hollywood After Hours?

[arbarks]

We will be attending the after hours event on 3/22, this will be our only Disney day before moving onto Universal. I've been stalking the reservations for several weeks but they don't seem to have any past 7pm on any of the party nights. Has anyone had luck going straight to Savi's when we're allowed to enter at 7 and trying to snag a spot? I called Disney reservations and they advised that it may be possible but I'd love to hear from someone who was actually able to do this. TIA!
