That's less a Rorona problem and more a Totori/Meruru/Ayesha/Escha problem. The big issue in Rorona, as with the earlier games in the series, is travel time.
However, to give Escha and Logy some credit, you can speed up your gathering time dramatically over the course of the game. When the game starts, you can gather twice before one day passes. Then you "research" and can gather about three times in a day. Then with more "research" later in the game you can gather about 10 times in one day. But there's never really 10 gathering points in an area, usually no more than 5. This lets you clear out all monsters and still gather in one day per map, though, which is nice.
