I would think that some of those that have loved FP+ from the start would be up in arms about even a hint of this happening. After all, wasn't one of the reasons there needed to be changes in the way they were given out was because of super users getting more than one paper FP for the same ride and keeping another guest from even getting one?
I'm missing the connection of holding FP back and allowing people to ride more than once. The OP scheduled a FP @ 4pm with a 7pm return time. Figure most people are already in the park by 4pm, if they don't want to ride TSM and would rather FP other things, and there's available slots lots, why shouldn't people repeat rides if that's how they choose to allocate their FP+ selections? Others had the same opportunity to get the FP for TSM but chose not to, it's still all "fair" since everyone starts at the same point.
ETA a disclaimer: I was at WDW last August and was not a pilot user so still used paper FP. This upcoming Aug will be our first time using the FP+ system so until I try it, I remain neutral.
