Thanks to this board, I had a very successful few days with the girls in Wan Chai, but I really like to try to push my luck, and see if I can get myself 2 bisexual girls that would play with each other in bed and play with me too at the same time.
Is there a way to easily spot girls that would be into group play at the clubs? I know I could get 2 girls back to the hotel with me but how do I make sure they are into group play (as in willing to kiss and have sex with each other) instead of just taking turns with me? (Seems that most of the time a Bro gets 2 girls into his room looking for group play, this is what happens as the girls really do not interact with each other if in bed together or even take turns being in bed with the Bro) I know The quick answer is just to ask them, but I wanted some more detailed advise by somebody that has done it before. Also for 2 girls, are the rates just double the regular rates as quoted by TonyToro, or I can offer less since they are together and should feel safer going away with me?

Good luck getting the full deal, you are more likely going to get 2 girls that will not touch each other.
They will promise it all but not deliver in my experience, the best I got was a quick muff dive (and I mean quick) from one of the girls and that was it.
There have been a couple of reports where it was all on but extremely rare.
The one I had in HK I got a discount was 1K for her and price dropped to $1600 for her and her friend.

You're right on all counts

hard to find

If I was on your mission I would look for a couple of girls who say straight out that they double-team, and then be very explicit in the negotiation before any discussion of money.  

... and as a consequence, looks and age become less important ...

If you go with that pragmatic plan you may get lucky, but getting two young goodlooking girls who are not just into each other and ALSO enjoy hetero sex, is like winning the Mark 6.  It takes time, patient persistence, and a lot of money.  

And, as we know, someone does actually win the Mark 6, almost every week

Here is my approach and even though I'm not a big fan of threesomes it has always worked for me in finding the right set of girls.

Rule #1 - Find your first choice girl and qualify that she is into girl on girl action.  Just be up front and honest with her on what your exact expectation is and make sure she gets it.

Rule #2 - This is where it gets a little bit more challenging and you have to trust your selection of girl number 1.  After you and #1 agree on your expectations, tell her to choose her partner for the evening.  Give her a budget and let her shop. I've always been very happy with their selection.  Let her drive and she will find a girl that is into it and you will know they are both on the same page since she is making the approach.

That's it.  I've used this method 8 or 9 times in my punting and civvie adventures and it is always a positive result for me.  Once in a while you get lucky and find a couple of girls that are already together and into each other, but that is rare as the other bros have said.

Worse case, you end up with your first choice and the two of you enjoy yourselves.

Enjoy man....

Yep. I have had a lot of 3-somes. Good times too -- but almost always the girls where just playful with each other but no serious bisexual activities. But twice I found true bi girls, and in both cases it was the girl I had picked who asked to bring her friend. Damn hot screwing a gal doggie while she is munching on her friends pussy!  

So, I think the best odds are to:
   - find a gal who says she is bi (this is hard enough).
   - have her pick the 2nd gal.  She likely already has a candidate in mind.

Thank you all for the advise. Brought it up with the regular girl that now visits me in my hotel room. Asked her if she had a friend. She asked "2 boys 1 girl" and I answered Oh Yeah! She told me she would get back to me and called back very excited just a few minutes later telling me how this good friend of her who is a "professional" (oddly repeated this a few times) who has done this MANY times, and that would join us if I would pay 1500 up from my regular 1200 for each girl for ST. she refused to send picks of the friend based on her being a "professional" as I would have to trust her judgment of this girl being very hot. No mention of any lesbian action was ever mentioned as the convo over the phone was hard to understand, but her enthusiasm calling right back full of excitement gets me intrigued... I will give this a try and report back.

This is what happens when you type drunk at 4am.... Of course I mean 2 girls one boy! Really need to make sure there is NO MISSUNDERSTANDING  on that point when I confirm tonight.....

For 3somes you are better to go through the net and seek independent providers.

Guys walk into bars and sometimes have ridiculous requests - Give a Golden Shower, I want to be a SUB etc,etc,etc.

Just an update. Nothing to report back as the 3some got cancelled. Called the girl a few times and when she finally answered she told me she would not be working for a few days.... Reading the replies it looks like  the opportunity may present itself one day and it's up to me to recognize it and make it happen. The surest way to go about it may be as chantik wrote to go online and seek an independent provider, but that's not my scene as I like the bars in Wan Chai too much.
