Notes

• Nacelle housings are accessible by turbolift and have control rooms directly above the nacelles with hatches for maintenance cycle access.
• EMH Compatibility is limited to several cargo-bays that are often converted to triage centers, and most of the medical deck.
• There are small lounges (equipped with replicators) scattered throughout the living decks, most notably in the enlisted quarter decks to give some spaciousness as that is the highest living density aboard the ship.

Standard Living Quarters:

• VIP Quarters - Arguably the most luxurious accommodations aboard the Isannah, they normally feature a large living area, and two attached bedrooms. Bathroom facilities are described as "spacious" which can only be applied to these particular bathrooms on the ship. They are generally arranged with smaller quarters nearby as very important people nearly always have aides and attachés traveling with them.
• Senior Officer Staff - Ample living area with an attached bedroom and dining area. The bathroom facilities are attached to the bedroom with shower/bathtub facilities.
• Officer Staff - Less spacious than the senior staff, but with the same basic contents, except a shower stall is standard (a few have bathtub facilities).
• Family Quarters - living area with attached dining area, one centralized bathroom and bedrooms attach off of the main room. Generally they are assigned due to family size, rather than ranking of serving crewmember(s).
• Enlisted Quarters - Bunkrooms outfitted from between 4-8 occupants, and attached bathroom and shower facilities. No living area, must use lounges located on the same deck. Normal occupancy is 2 in the 4 bed rooms, and 4 in the 8 bed rooms, unless a shipboard emergency is underway.
