KingB, can you add me?
As for the letters: In AC and probably WW, letters were delivered at 5PM and [?]6AM. I can confirm the 5PM delivery time for AC:CF. Around that time you can see Pete, the postman, delivering letters (on foot too!) around town and you can talk to him.
For trees: I can't confirm the 100% rate for axing a tree and planting it there, but I can confirm that very rarely if ever does it grow in a place where you can't walk all the way around the hole the fruit is going into.
