Yes first grab RSR FP on MaxPass as soon as you get to a stopping point inside the turnstiles. You could ride GotG first, but the app will tell you when you can get your next FP after pulling RSR & it won’t be too far out so you don’t have to rope drop rush it if you don’t want to. Soarin is a great option for your first ride since the queue is in the area where they allow people to wander pre-RD and I’ve heard it’s possible you get going in the queue before the park officially opens. But if Soarin isn’t a huge priority & TSMM is then that is another option.
There aren’t a whole lot of DCA rides now that don’t have a FP that bog down with the lines. TSMM was notorious for getting lines that built up, but it does now have a FP. The next biggest culprit of that is the Fun Wheel so that’s another reason to head up to TSMM & get that & the Fun Wheel done, but if you’re going after Jan 8th the Fun Wheel will be down for refurbishment until summertime. Luigi’s Roadster Racers is the next one I can think of that might get a wait that doesn’t have a FP but even then it’s never near as long as TSMM would get.
