Hey everyone..

Ok so longstory short, like to fly ( All in J) from EU to HNL, spend 10 days with family, then fly to Japan, spend 2 wks, then fly back to EU. One ways appear to be cheaper than rtw, about 4.5k ish. Since I only want these two destinations, is that the way to go? Is there a cheaper rtw ticket that restricts u to a few stops? Just wondering how to accomplish this?
Thxs
