Yes... I had my three regular 60+10 FP's booked for each day as of 7 that morning. I'm assuming they (DSS) could see them when I called DSS at 9AM as the DSS agent mentioned he saw the time of one of my ADR's and worked my evening FP around it. He did mention that he could see the day that they allowed us to have a duplicate --- that we were spending the day at Epcot and then he made the FP + that we purchased at Epcot --- so I'm assuming he could see it all. Think it may be nothing more than THEY can't book 2 duplicates when doing special FP+ booking but they don't dwell on what you already have booked at 60 + 10 days since they're totally separate from the offer. Doing all 6 bookings for a day at 90 days is different as they are all booked at the same time and I'm guessing they're all special. Not sure but that's my guess.
