TSMM or MFSR first?

Have a 9:20 SDD fp. Want to use mfsr single rider twice due to 2 non rider kids. So what do I head to at rope drop?

I don’t have experience with the star wars part - but my gut says TSMM because a lot of people would be heading to SWGE. It would be best to rope drop something that is not in SWGE.
