By adding the qualifier: "If you've been on the ride", it seems as if you are asking whether the ride is "good enough" to warrant a FP. But that is not the test. Efficient FP usage is about line avoidance. For the foreseeable future, the Mine Train will command a big line. So if you want to ride it, get a FP for it as many times as you think you will ride it. I might think that the Tea Cups is a better ride (just making an example here). But I would never get a FP for that because it would be an inefficient use of time.
