People will travel as they see fit. That's all there is to it.

Here I'll give you an example of my play style

When I do leves, depending on time and if I do them alone or with people from my ls, I will usually run from Ul'dah to Gridania to grab leves and wait for everyone else to be ready. Or if people are all on at that moment we teleport as a group. We decide where to start, Treespeak or Nine Ivies. We of course teleport to both camps as there is nothing to really interesting to look at on the way. The scenery is beautiful though. The teleport also saves on time since people just want to get leves done and go about their own business. Everyone is happy.

When I do locals, I will walk to every camp to turn them in. Why? Because I think it's wasteful otherwise and I usually have time to do so. Party somewhere? I will teleport to the aether and walk to meet the party.

So there is how I travel. Everyone is different. You do whatever is convenient for you, as it should be. Options are a good thing.
