Thanks for the reply, and yes I have called or texted on several occasions, and either my bad luck or whatever, the girl I wanted was not there (gone on vacation , left or whatever) even though she has been listed on the schedule for a while.
I have stated the same thing before, the best option is to call or text, and if the girl you want is not there then move. After a while you get tired of not being able to book the girl you would like, so I just gave up. It's a sad thing, as I like the spa.
BTW: Anan re appeared on their web page for a day or two, and now she is gone again (checked yesterday), but she is still listed in the schedule list. I did not try to book Anan, just to be clear.
