That all depends on park closing time and when the show is. They aren't always at the same time. Most of the time we've done it, park close is at 9:00pm. F! is often at 9pm too, especially in the summer because it doesn't get fully dark until then. But don't hold me to that, because the nights we did TSMM at the very end, we didn't pay a ton of attention to what time F! was, since we weren't going to do it anyway. But we've had many times where we walk into the queue for TSMM at 8:50pm and we walk right on. In fact, once we even just went around again, since there was nobody there. TSMM is DWs favorite ride in all of WDW, so we make a point to get on it as often as we can, and this has been a very successful strategy for us. Can't promise that'll happen this time, as the lack of FP+ may change peoples' habits. But I'd definitely give it a shot.
