I took some time off work last week and had a chance to explore a little bit. I got a lot of helpful info from this forum, so I thought I'd share some of my experiences.
Saw Alyssa last week. She greeted me at the door with mask on and she looked a lot more asian than I expected. During the session when I asked her to take the mask off, she looked a lot more caucasian. I went through quite a few reviews of hers and I found this one to be VERY accurate.
Review - Alyssa @ Bellagio Almost as if it was virtually the same session I had. Started massaged, discussed extras + tips, then immediately dropped her clothes before continuing. The closing of eyes and making weird facial expression during HJ also happened -- HJ was good, so it's not a big deal for me. I would say her massage is even weaker/softer than that was described in the other review (speaking as someone that can't really handle hard massages). My experience is fairly neutral and would likely try others before repeating.
I saw Clara 2x back in around March / April. Even though she is not experienced, she puts an effort into the massage. She tried to be sensual during the massage -- will get on top of you and lean real close (can feel her hair on your back / shoulder / head). Her HJ is not as good as Alyssa's. It seems as if she could not find a rhythm and is always trying to adjust; need to provide guidance to finish off. I had a fairly good conversation with Clara during my sessions. It made the experience better which was why I repeated with her already.
Overall, for this spa that seems to be a mishmash of what they provide, I find it a little surprising that the massage itself is not at a higher level. I am considering trying Jennifer just for the massage -- but hesitating a little bit because a lot of what is said here is highly glorified.
