They'd done their homework.

For two days, they'd tailed her.  They watched where she went (not many places, but it was a great primer on how to get around the vast city), who she met with (just a couple of people, but nobody familiar - not that anybody really was at this point), and what she did (mainly talk).  There was a pattern and it was Ghost who finally worked it out. 

All six of their group were sitting around the wide-open living room area of the suite.  Nine was rummaging through the plastic bags from radio Shack, occasionally mumbling a "yes" or a "hmm, that should work".  Tom and Ghost had taken off their coats as Ghost finished giving his story about the girl in the lobby.

As far as hideouts went, it was pretty sweet - no pun intended.

"The JW Suite is the signature suite of the New York Marriott Marquis featuring a contemporary style, large floor plan, mahogany piano and up-close views of the NYC skyline."  So the brochure in the room had said.  Nobody was quite sure what a "piano" was until Nine referenced the interactive database on the small computer he took from the house.  It turned out that the piano was a large musical instrument, a string/percussion hybrid.  It was pretty, and the sound clips on the database were varied and interesting, but nobody could play it.
