Just wanted to report back... and also say thank you.
I used SDFP/4th FP on my last afternoon in January but was still getting my sea legs under me so I can't recall what I booked under which. I borrowed my roommate's MB, but that won't typically work as she's usually with me.
This trip, I booked with Priceline, which automatically put two adults in the room, so I had my own (I was both my first and middle name.) If I had thought about it, I would have linked it to a fresh
MDE, but hindsight and all...
Anyways, I used SDFP a little more. Sat AM, I had prebooked FPs at Epcot and then managed to totally jack my touring plan by trying something different that didn't work lol. Plus, Frozen was down... I got to MK with a prebooked for JC around 7ish. Used it and got one for Pooh, and when I got to the kiosk, I found a "multiple attractions" as Pooh had (supposedly) gone down. So I booked Pooh again, and Pirates and Buzz, I think? I had really wanted BTMRR, but it wasn't available. However, the "multiple" was valid for it, so that was perfect. Since the Pooh had converted, I was able to get another on the app (IASW I think, which had a 30 minute wait... it's my favorite so I was glad to be able to get on.) Weirdly, the second Pooh also popped over to anytime a few minutes later, yet the ride was definitely up when I walked past it right around the same time.
Anyways, I attempted BTMRR but both Pan and Space were down - leaving the FP line completely full and into roped turns, I'm sure from others redeeming their "multiple choice" passes.
Still, having the three made a very crowded evening go much better.
Sunday I had my FPs prebooked at MK in the evening, and IMO this is where SDFP really shines. I was at DHS in the morning and rode TSMM at RD, then booked GMR & ToT with SDFP. Crowds were weirdly light so I did ToT twice (walk-on,) went back and did TSMM with a ten minute wait before doing GMR, grabbing Starbucks, riding ToT and scooting out.
That evening, I was able to augment my MK biggies with Under the Sea and maybe something else? Can't remember. I did finally get to ride BTMRR, lol, as one of my prebooked.
All in all, it felt a lot closer to original FP and like we might finally get some productivity back. Next trip is a multigenerational group of 13, and I'm weighing the idea of prebooking for "full group" rides and using SDFP for the split stuff. Just question the coordination...
