who would be ready to travel  to you
 and your friend  
Bur such things require connection and if it is upscale provider she possible would ask first meet just one of you by turn first .. then set up threesome.
 Or just meet 3 of you at nice restaurant to flirt and have hot times ..
 so would know you how you would approach her together..
 It is very hot scenario i love to do and done.

But of course even dinner to start with two of you is not free time  
 Time has to be appreciated.
