MSC Monterey's Promenade Deck Midship Casino [Palm Terrace], Photo Gallery which lines the hallways of Aloha Deck & stairwell lobby fwd of the Reception Area, and Doctor's Waiting Room.
The Palestra Gymnasium is down on 'A' Deck, rather crummy looking and in the middle of what appeared to be crew cabins [cabins along the outside of the vessel with the gym where inside cabins would have been]. I did not take any photos in there, due to the sole occupant being spread eagled in the middle of the floor - April 2006
