We stayed offsite last year the 4th week of September with 4 day park hoppers. I was up every at midnight for every 30day out night of our trip to get 7dmt fp+. I managed to get it for 1 person the first day I tried. The other 3 days there were none available. However, last year the ride had only been open for about 6 months when we went, so it might be easier this year. Also, through randomly checking and subscribing to the A&E/7DMT FP+ thread I got what I wanted and found that had I wanted to I would've been able to get them for every day of my trip. True, I only wanted them for 2 people, not a big group. Just be aware even if you don't get them at the 30 day mark it's still entirely possible to get them later with a little persistence! Good luck!
