It's hard to do with street girls, nor would I want to given the level of service most SGs provide. It's easier to do with bar girls. It should cost about $200.00. Chicas at AB, CC, etc. do it all the time.
Hotel del Santiago would be my first choice in the Zona. But I'd much rather go to La Mansion. Many chicas prefer to use the hotel associated with the bar where they work--especially if they don't know you. Leva you are going to do a CC girl. Adelita's hotel also has all night rooms.
There are guys who've done this. However, most chiacas aren't into groups, other girls, etc. so it can be hard to organize unless you're a "seasoned vet" with "party central" know how.
Finally, most vets--for a good reason--will tell you to first do a regular session to see how you click with a chica before trying to do a TLN with her. It's very good advice.
Sampson aslo gave very good advice about being sure you establish the "ground rules" ahead of time. Like when the TLN starts and ends, plus what sevices she is to provide (dfk, bbbj, etc.)
If money isn't a limiting factor--and you must have girl-girl action--then contact an escort agency. You're more likely to find real girl-girl action that way. I somewhat doubt, however, that you'll get escorts to provide group action.
