Bringing my girlfriend to Pattaya

Hey,
So this might sound strange to some of you but my girlfriend is bisexual and also quite open sexually and has expressed a lot of interest in going with me to Pattaya, mostly for threesomes, but i would not be surprised if she find some girl for some 1on1 time without me as well.

She is filipina but has been living in a western country since she was a child so thai women always assume she is thai at first (since there is a lot of thai women in the country i am from). Just mentioning this in case some you think it will make a difference in Pattaya.

So i was just starting to think, how will the girls react to me/us coming into the bar with a women that they will mostly assume to be thai at first. Is it bad news? Will it be easy for us to get threesomes or will it cost us double and so on?

Basically, i am asking if you guys think this is a good or bad idea? Should we just go somewhere else together? Also Angeles City is out of the question for different reasons.

If it make any difference, we are both in our mid 30s.

Thanks guys.
