I would guess (just guess) she is not interested in handling lots and lots of emails before she is in the area knowing the majority won't come to anything and when she has a pretty detailed profile.
Not defending her but she may know she will get lots of bookings and can be a bit precious with her time before she arrives.
I looked at the pics and wondered whether the good bits were still good on her body and if the face still looked natural at all.
The recent fb is a bit dodgy - e.g. 3 over the top by the same person - but...
I would have thought if she has really got your interest then booking request sent Sunday afternoon could attract her attention.
Just my take on trying to see her in a positive light so you won't die wondering.
