I don't think they mark them on the maps because depending on the day they might not all be open. From what I have red online though they are all prety easy to find though.
The park maps have the FP+ kiosk locations on them, but not all of them are always open/operational, and apparently, sometimes others are open that aren't on the maps. So...that's awesome.
agreed - we're going down in 11 days - in 10 days I'm going to look at Kenny's site and Josh's (easywdw) to check their info - write down the 'current' locations of the kiosks. Once we get down there we'll keep our eyes open and make notes if we find ones not listed. We've experienced the disappearing/ moving kiosks - it can be very frustrating.
