Our FP day was yesterday. My husband and I logged in at 7AM on different devices (we both used laptops). We'd divided up the list for our 6 day stay (4 people in our party), and we used our shared
MDE account. He took our 3rd and 4th priorities and went for those first, and I took the 1st and 2nd ones, and we split up the rest.
He went for SDD (60+5) and was only able to secure FPs after 1PM. I went for FoP (60+6) and had no trouble securing the time I wanted (10AM). He next went for 7DMT (60+1, just in case he was able to get it) and was able to secure 4 FPs for 3PM. I went for 7DMT for (60+7), which as expected was easily available, so we cancelled our (60+1) FPs.
We filled the in-between days with FPs for non-headliners at the parks that we knew our kids wanted to experience (like Haunted Mansion). For those, we were able to obtain the FPs at the times we had hoped for and were done by 7:30AM. This was a marked difference from our FP booking experience for our October 2018 trip (the website kept crashing, etc) - yesterday was SO much better.
After we booked all of our FPs, I "fine-tuned" the timing. We logged in last night too and saw that 7DMT was still available for a party of 4 on (60+1), which corresponded to 2/2/2020, after 3PM. Surprisingly, SDD was also available (after a few refreshes) on 60+5.
Good luck everyone!
