I personally hope that if it is, that there will be an option to skip it. I think that would be the best way, because it might be cool to take in the view the first few times, but then it will get lame. But more likely I assume it will be like MW, just instant travel you pay for. But either way I am not big on any fast travel method(I like running from place to place) so it not a big deal to me.
Thats what I thought too. Its one of those things that just isnt fun anymore on your 20th character.
So I think it would be best if you just travelled along the road at a faster pace than normal, but with the option to skip that part and go directly to your destination.
I agree with the other posters on this thread who would like it if payment is required to use the carriages.
