My apologies for not realizing you were being serious.
We are a "wing it" kind of family. We do not book FPs in advance. I will go on the app the night before and book 3 for the next day but that's as "in advance" as we get. Of course, that does mean that we can't always get on the most in-demand attractions but we're okay with that.
For Mine Train, I'd suggest doing rope drop on your MK day. No FP needed. We've done that and it was no problem at all. Peter Pan might be a little more challenging but if you go there straight from Mine Train, the standby line might still be reasonable. In general, we find that we can knock out several Fantasyland attractions in short order if we are in at rope drop. That first hour after the park opens can be golden.
Don't forget to check which parks have EMH if you are staying onsite. If you are not staying onsite, be sure to avoid the park that has EMH each day.
