DHS has added locations that aren't listed on Josh's site:
Echo Lake - Fp+ signs direct incoming guests to Echo Lake because Sid Cahuenga's is restricted to onsite guests and Swan/Dolphin guests. The Tip Board only has two kiosks and relatively few CMs - probably because they don't want a horde of guests blocking the main intersection.
The Hat area - closer to American Idol in the mornings and they spread out later in the day.
***Look for Fp+ CMs who are wearing the teal blue shirts with The My Magic Mickey Symbol. There are a lot of audio/lighting techs who carry iPads and they can't help with Fp+.
