There is a (newer, larger, nicer) SN lounge in terminal A, if you somehow end up over there.[/QUOTE]
The Sunrise Lounge is at the far end of "A" Terminal in the section that is actually called the "T" Terminal where flights depart for Africa. It includes separate "sitting" and "quiet/sleeping" sections. There are about a dozen cubicles in a line with single-size foam mattresses. Very convenient. It's one of my favorite lounges.
