Saw the visiting Maria, and I have nothing bad to say, but I certainly wasn't blown away.  One of those middle of the road experiences, that sometimes may be chalked up to no chemistry.  YMMV.  I certainly didn't feel cheated (especially at 250).  Don't know if I would repeat.   It might be one of those that gets better with frequency.  She was pretty, accomodating, not particularly rushed.  Was a tad heavier than her pictures imply and was not as open-minded as implied.  Enjoyed myself, but I don't feel compelled to rush out and tell people about it.  If you are in the mood, it is probably worth a shot.
