Transportation within Skyrim mainly includes horse rides, walking, and boat rides across lakes and rivers. The cost for horse rides is around $30 per day, and boat rides will cost $20 per ride. It is important to note that some places may require a permit for entry, which you can obtain from local towns or cities. Travel time may vary depending on the distance and mode of travel, so make sure to plan accordingly.
If you have more time, consider visiting other areas such as the Thieves Guild, the Mages Guild, or the Imperial Legion.
If you have less time, lessen the number of activities/locations per day, and prioritize based on personal preferences.
