Okay
@Cluelyss &
@hiroMYhero - I tried it yet again today at Epcot. While I suppose it's possible that it only works for me through some kind of glitch, I did test it with two different sets of AP's, so two groups of 2. For the first group I booked:
905 Pixar Film
1005 Turtle Talk
1210 Test Track
We arrived at the park around 12:30 and went right to TT. As soon as we scanned, I used the same process I had used in the past (Using +, ignoring the "you can only have one of these a day") and was able to get Illuminations for those 2 people.
For the other group of 2 I had:
1255 Pixar Film
155 Figment
300 Frozen (yes, shockingly, I was able to get FPP's for FEA when I chose them yesterday afternoon!)
We didn't ride any of the Tier 2's (or tap them) - actually spent the entire time playing Pokemon Go around Epcot and ate lunch at Electric Umbrella while waiting out the pouring rain. We rode Frozen right at 3. I tried to get another Tier 1 for those 2 people but there were none left. However, I was able to use "Change Party" to transfer my Illuminations (Tier 1) FPP from the first 2 people to the second 2 people (so it did let them get another Tier 1 since their two Tier 2's had expired but were not used). I then went in and cancelled Illuminations for them as well (since we left by about 4pm).
I do have some screen shots but they're really no different than what I've done before. If it's a glitch, then it's a glitch for 4 members of my family, not just me. If we go to HS this weekend I'll try one more time!
