Osaka I won’t even think about private transfer
the last time I did is take train to near by hotel then take cab

cos luggage heavy to drag to hotel . but that is when my kids are younger .. but now they old Liao .. all take train then walk cos they can handle the luggage themselve
Sometime you also must see location . In city I won’t bother, where train easily can get to places
but bird don’t lay **** place I will arrange cos I have enuff pple in my group to get a 7 seaters to split cost
cos sometime detour train ride to next location , the total train cost for whole group might not be worth it .long time and expensive . Might as well get transfer .. save time .. at slightly incremental cost
