In theory this would be anywhere, but the game here is to roll up with super hot open minded girl, and use her hotness to have other open minded and horny girls approach her, me and her,or just me, and secure some action with the 3 of us?
I know this sounds a little corny, but where should we go in order for this to happen "easy and naturally"?
Maybe the answer is the place with most hot,open minded bi-girls in the world, but I am not sure where this might be.

Europe is preferred. US a possibilty. Mardi Gras or other similar gay events around the globe are not what I am thinking of.

Think going to bar/cafe/lounge/hotel-bar/night-club type of events.
My first thought would be gay/lezzie bars in scandinavia or CR, but then we would be actively pursuing our goal, and some or all of the fun would be out. (But yes, to quote Roosh, my d... would not feel the difference..)
We are both tall, european/caucasian style.

Kiev is good for that.

Why the US. Nowhere else are women so bicurious. European girls, while often trumpeting gay rights, are conservative in their own sexual identity. The vocal feminists dominating the media and preaching fluid sexual identity are a vast minority and nothing you want to bring to bed.
