Dh and I stayed offsite the week before Easter. It was level 10 super crowded the whole time, but we did really well with FP+. We booked our FP+s at 8:00 AM right at 30 days. I would have been online at 7:00 but our power went out due to a storm. I got everything I wanted for close to the times I wanted except for FEA. My 7SMT FP+s were for 11:15 PM. I didn't really want them so late, but at least I got them. Granted, this was all pre Pandora.
A couple of weeks later, the opening time for MK was switched from 9:00 AM to 8:00 AM (opening up a whole new hour of FP+ times), and I was able to switch my 7DMT FP to 8:55 AM, which worked much better for us.
I also randomly found a FEA when I was checking one day. I would have had to give up Soarin' to get it though. I decided to keep Soarin' as it's DH's favorite, and he hadn't ridden it with the new movie yet.
We also used SDFP in all the parks with old magic bands. We found great availability on almost every ride. We'd rope drop, ride 2 or 3 rides then hit a kiosk. The strategy worked very well for us over Easter Week.
