Just adding in my experience. We are going on 8/20, so I just booked FP at the end of last week. Now, we are only doing the party so I don't have the 60+ to rely on and I wasn't figuring I would get 7DMT, but I have gone in a few times to try and modify things, and there are hardly any options after 3:15 p.m. when I do so. I have three more people to add to my party who haven't bought their tickets yet, and I am worried about being able to add them in later given what I am seeing as hardly any availability right now. I'm wondering if they will drop more at some point. I'm a pretty wise FP booker with mutliple trips' experience and I haven't seen this little availability ever.
