I would say maybe you might want a FP for Turtle Talk if you really want to do it? With FP+, if more people are getting FP for Crush, then you might need to wait longer without FP?
I can't imagine waiting 30+ minutes for Figment, never seen a line there, but don't usually go during super busy periods.
Indiana Jones was interesting on a non-busy weekday afternoon last month: there were hundreds of people lined up to enter with FP, but no line to go in standby. FP line presumably slower because people needed to stop and scan the Magicbands. Meanwhile the standby line just flowed right in, and there were plenty of seats. I don't think FP people have a special seating section? It was bizarre to see that long FP line on the left while people just walked in on the right.
