I need some advice on an issue that a MPUA might know some secrets for. I'll try to break it down as simply as possible

My brothers girl friend has a best friend who's a HB. In the past I tried to encourage my brothers GF to hook me up on a date with this HB. I almost managed to get a group meeting thing going with the four of us but then this HB cancelled. I didn't proceed any further, unsure of what steps I was supposed to take.

Anyway my bro's back home with his GF and this HB along with some other female friends of theirs. After finishing work on Saturday night I'm planning to go and meet them all at some bars, clubs etc, and then give them all a lift home. To me this sounds like a good opportunity, a bunch of drunk girls, me sober and my bro back from London.

Anyway can I get some advice on finally getting this HB? Thanks in advance
