David Krichavsky wrote recenlty about accomodation of USO tours. He said that they were sleeping in Saddam's former palace.
The coaches stayed in “DV” quarters, which are on-base accommodations for “Distinguished Visitors.” These quarters can range from having an extra pillow on a standard-issue Army cot in a barrack-style room to comfortable single rooms for each member of the tour. The highest-level DV quarters were located at the Joint Visitors Bureau (JVB) Hotel which is former palace of Saddam Hussein. Some soldier went to ask for signature on giants jerseys.
The five coaches had to stay in one room with bunk beds. The reason was that Vice President Joe Biden was also in the JVB Hotel staying down the hall from the coaches, and the rooms between them were needed for Secret Service and key VP staffers. The Vice President had a nearly one-hour exchange with the coaches.
