There's still rope drop and/or closing time - although rope drop seems to be getting pretty crazy for any type of headliner! I would imagine, even if they limit re-rides through FPs, they can't really limit additional rides through standby.
I feel like I remember that the one original intents of FP+ was to try and level the playing field with the paper FP uber users. It doesn't seem to me that Disney is so good at trouble shooting unintended consequences so maybe they didn't think through how more experienced users would be able to utilize the system, especially with the app. So, anyway, we had a snow storm last week and we were supposed to have 4" and we had 12" - the weather man said the storm "over performed," which I thought was kind of positive way to reframe being buried in snow...so anyway, we've done very well over the years with FP+, but I don't see myself as a commando but more as an "over-performer," lol.

I just hope whatever they roll out has some measure of clarity, logic, and flexibility. Ok, even as I write that, I realize I'm probably being overly optimistic!
