personally, i was thinking that mauville and verdanturf in particular were close. they seem kind of closely linked (not just talking geographically) and have a well-worn path between them, with the daycare there. i imagine back-and-forth between those two is a pretty regular thing, so a trip maybe takes like… an hour or so? if that's walking speed that's about 3 miles. other locations tho don't necessarily scale the same way as in the games.

that was just the assumption i was going off of, anyway.
