I can travel from Solitude to Riften in an in game day. Worst of all, an in game day is like an hour and twelve minutes in real life. I mean, it took me two hours to walk from my middle school to my house if I missed the bus. An entire province shouldn't feel smaller than my hometown. Because of this, sometimes I prefer fast traveling. I mean, when I just started the game, I really wanted to see everything, and it felt like a long, harrowing journey to go from one city to another (especially if you are not using your compass). Now, I've seen everything, and it doesn't feel like an epic journey to go from one side of the map to another, it just feels like a minor inconvenience. Again, I'm not blaming Bethesda per se, I'm sure making 16 square miles of terrain that detailed wasn't a walk in the park, but it really doesn't feel like an entire province. In fact, I kind of wish the game was set in a single hold but still be 16 square miles, Let's say, Whiterun hold. (keep in mind, TESIII:Morrowind was only half the province of Morrowind, so it's not like it hasn't been done before). Yes, I'd still be able to travel the entire hold in a real life hour, but it wouldn't feel as bad, it wouldn't feel like Tamriel was just this small little Island.
Also, keep in mind, lore wise, Skyrim has many more towns and villages that were not in the game because there is only so much you can do with 16 square miles. Making the entire game in one hold would allow the developers space to develop these cities more thoroughly. Maybe Whiterun city could be as big as the Imperial city in Oblivion, instead of just this small little fortress. Maybe Riverwood and Helghan could be as big as Whiterun is now. and maybe the smaller cities that were cut from the game could be as big as riverwood and helgan. Again, this would make the world of Tamriel feel much bigger because it's kind of ridiculous to have an entire province with only 5 major cities
