That’s the trouble with the Epcot FP+ choices. You’re right about the tiers. There are so few good tier 2 choices that we generally make our FP for a different park and rope drop soarin or frozen.The OP already has a Frozen FP, you can not get TT or Soarin' while you have Frozen. That is unless something changed this year and I don't know about it. That wouldn't surprise me, that is me not knowing about it. With that being said, it would depend what interested them. Also when you are going. I have never had to wait for crush and we normally get good seats. There is normally a small wait for Living with the Land and sometimes Imagination. That really leaves Spaceship Earth.
We always use one on the character meet and greet here since FP+ choices are limited. It's not a bad 10 minute use of time if you don't have another use for your fast passes.
