So we know that you can gat to laugh tale by get the info from all 4 road poneglyphs. But do the strawhats need to go to loadstar island to go to laughtale.
Apparently no, the SH will get there because of plot or because there is the lost road poneglyph, but if you already have the 4 of those, and therefore you already know Laugh Tale's location, you can get there without having to visit any other place.
