We've just scratched the surface of all there is to say!
So let's chat about return times. CMs are outrageously strict about coming back before the return time. I've had to wait outside the entrance at 6:59 pm for a 7:00 pm window. On the other hand, I've used FPs that are days old.
How do you use your FPs - right away, soon after, days...months...years later?!
