Think about it, traveling from one town to another doesn't seem to take that long, it's quite safe, you really don't need to worry about being mugged or anything, you have powerful creatures to help you out (having a machamp bodyguard would be sweet), most everything seems to be pretty affordable and easy to access, and you can travel to different regions easily as well.
You also have what basically amounts to free Inns with the poke center so you really don't have to worry about paying for lodging or food.
