Depends on when you are going. Touring Plans was giving me a 28 minute wait if I arrived at TSM by 9:04 on April 21. We arrived at the lineup for bag check at about 8:50 am, and were in the park by 9 am. We then POWER WALKED directly to TSM in about 90 seconds, and the wait time said 20 minutes. In reality, we waited about 7-8 minutes tops. However, by the time we exited the ride, the wait time said 70 minutes. We then proceeded right to Rock n Roller Coaster an the SB line was about 20 minutes (I thin we waited maybe 10 minutes?). So I would definitely recommend getting a FP for TSM later in day and going straight there at RD to ride standby. If you are not in the park by 9:10 (or ten minutes after opening), and you do not proceed directly to TSM, then you will be looking at a 30-40 minute wait, and R n R will also be 40 minutes by the time you get there. If you plan on doing Tower of Terror, I would recommend doing it after R n RC, as the wait time will still probably be posted at 10-15 minutes, so you should be able to walk on a couple of times.
