What time of year are you going? First I’d keep an eye out to see if DHS has any morning hours added and try to snag a FP for one of them that way. Otherwise, if it were me, I would rope drop one (even if there ends up being a little wait, just to get it off my list) and save the other for later in the day before park close. The lines for SDD and MFSR get much shorter at the end of the day.
