SDF has 50+ semi private rooms (cubicle plus curtain) then 3 floors of private sleep rooms. There are also 2 recliner rooms.

ANC = 6 semi privates+ a recliner room.

ONT = has a bunch of semi private rooms and a few privates but many of them are reserved by sort crews each night. Also has a recliner lounge room.

Wherever you’re based you’ll get a locker. If not SDF, you can buy one of those self-inflating camping mattress pads and a pillow and find a place to lay it out. Slap on an eye cover and some ear plugs and you’ll be able to squeeze out a nap in most places if you can’t get a bed. Keep in locker.
