Pfft missed it was multple choice.
Anyway, i will mostly fast travel or horse & carriage if i dont know the place. But if i feel like some fun for a couple of hours and it usually does take me a few hours because i get sidetracked, then sidetracked, then sidetracked, i will do it, also walking places you find so many landmarks etc
But if im wanting to play out a questline or whatever then fast travel etc will be my choice.
(Just an example last night it took me 2 and half hours to get to the dark brotherhood after doing the initiation, i did like 3 dungeons and gained around 8 quests on the way though aswell as picking up god knows how many herbs and finding many different locations. Was alot of fun.)
