It may sound like I am a shill for SB but it worked out for me on my last Vegas trip.
I sent out a bunch of messages basically saying I was there for a week for work and
got some some discussions going. YMMV with SB and there is a lot of flakiness
but it is just a numbers game.
Ended up setting up a date with drinks and some site seeing before hitting the hotel
so it turned out to be a fun excursion.
