I also tried 花花 last week. Looks not bad and breast good shape but she was very tired and 是是但但....

Try 安琪 from 靈子. she was wearing the same what siuliee describe, but she not change in the room, she come wearling like that o! The short shorts shorter than her top, so look like no pants with black stocking. Lucky hotel guard did not stop her.
i find her quite articifical, not my type. And she was rushing for another appointment.

小欣 from 小婷 was enjoyable. She is thin but has 气质, and nice dress style. not so open to me but enough

The big problem is not whether 保安 outside hotel, but if the elevator need key card. if key card then you have to fetch the girl or she wait for someone to also take the elevator, but waiting means it will attract the保安's attentipn

上次问 agent 要了莉莉。 来了一位很漂亮的技师，但我怀疑她不是莉莉， 因为她没所说的 172高，问起来说没做过商场 model, 说来之江蘇，不是上海。 她比较像是彬彬（江蘇, 21/169, 36B及手, 48kg, 身型勻稱, 長髮, 清純嬌羞, 小鳥依人型 ）。她样貌很不错，我就算了，Part 1 不太好，Part 2 好反映，1000成事。

We all have same experience with Wang Yun! Say her breast not comfortable due to period! Agent say she has told Wang Yun not to ask for too much money and provide good service.
彬彬 from same agent is much better
