Mom Gabriel from Honolulu wrote in July 2012: "They do have a "nursing" room for all you mama's who want to nurse in private. Just be prepared to sweat up a storm. You might as well nurse outside, it's cooler out there. The nursing room has a wooden rocking chair in an unconditioned, cell block type room."
Note: They have a little red phone outside that you pick up, then someone answer on the other end open the door to let you in. This prevents anyone from barging in on you unexpectedly.
