Traveling light is really always the best way to go.....there are no disadvantages,and plenty of advantages. Unless you really need specialist sports gear etc....even then,you can usually hire it.
The only people who can't see this are those who travel with too much gear..and even most of them learn from their experiences and go lighter the next time.
I have never, ever met a traveler who says "My bag is top light. .I want to bring more stuff next time"
Maybe only of you stay in very flash hotels and take taxis everywhere does it not make a real difference. ..
