I can give you an alternative method: http://www.tesnexus.com/downloads/file.php?id=4520 will add some cool transportation (by horse and by sheep) method, as well as what may be more useful to you.. teleporter for the Mage Guild much like in Morrowind! But I think you need to be a member of such guild to use the teleports.There's another mod that adds teleportation platforms to the mage guild, those should be usable by anyone, but I don't remember the name :/
Thanks Dirich. I had already considered some mods similar to what you are describing. Maybe for my next char I'll use something like that.
My Automatic Timescale mod - which is also integrated into Real Sleep Extended - has a specific timescale setting for fast travel. Set this high, and fast travel will take more time. You could also consider my Map Marker Overhaul, which has the option of restricting the allowed fast travel distance, and/or to limit how much fast travel you can do within a certain time.Edit: Noticed Tomlong75210 already mentioned it.
Thanks NiceOne. Yes, I DL'ed your mod which Tomlong suggested. I already am using your map marker mod. Fantastic work. Always impressed by the quality of your work. Many thanks.
