As the previous poster stated, it is very easy to get from town to town, even at rank 1, as long as you stay on the roads. I will add however that there is one place where you do need to be a little careful at times. In the "low laying" area just outside of where the port is in Thanalan to get to Limsa, there are at times r46-47 Dusty Mongrels (hounds) that will aggro you. Also in that same area at the bottom of the ramp leading up to the main part of Thanalan there is occasionally an Ahriman or...one of those short thf looking mobs can't remember the name of right now. But other than that short 30 second run, you should encounter no problems as long as you stick to the roads.
