All of that info is pretty accurate. However, recently there seem to be fewer ladyboys at Ayala. The ones that do show up mostly meet up in a group at Bos coffee sometimes. Very few female freelancers there, most of those, the few that there are, circle around the Social bar up on the 4th floor. Some ladyboys also stay around the center courtyard in the terraces, and a few are shopping through the mall. The difference between ladyboys in the mall and gg are that the ladyboys will almost always smile at you, so you shouldn't have much trouble meeting up with any you see walking anywhere in Ayala.
All around the Mango area streets and Ramos st, even Fuente Circle, a person can meet ladyboys walking, all are friendly and will smile, say hi, and are interested in talking to you. Somewhat unlike Thailand, many would be willing to go for free, or a very low price. Also, some are willing to introduce you to friends, lb and gg, but usually for P4P.
Online, DIA, Fillipino Cupid, and Pinay Love all have ladyboys profiles. Almost 100% will be interested in meeting.
