My answer for you:
If you wanna do SDD a handful of times, and TSMM handful of times, and then get on RNR's first run of the day, along with possibly another run on RNR or TOT before eating a really nice breakfast*?
Then, the answer is yes.
*Chances are, you'll get some really nice photos, and a possible spin on Star Tours before breakfast as well. Another plus is that you can essentially cross TSL, and at least one spin on RNR or TOT off your list for the day. That may make your needed fastpass choices after 9am look a LOT better?
