Just beware if you are using the men's locker room. There about 8/9 lockers located near the entrance of the changing room that are in sight of anyone who is in the main hallway, man or woman. At least that was the case in October when I stayed there for 5 days (Paris). Don't want any men giving any "free shows" unexpectedly! Nice sized fitness room. I don't know about the cost because I'm diamond. Spa has sauna, steam room and a mixed bag room (steam plus something) and 2 hot tubs if I remember correctly!
