I am aware I did not specify that it took two weeks, and that I was vague about it.
However, my post was in response to yours saying 'If we stayed another day then by pure random chance etc. etc.', when it was clear that it took longer than a day to get to Marienburg the first time around, at the noted repeatedly accelerated breakneck pace of getting to Marienburg. If the pace is noted to be reduced, not necessarily by the weather, but by less of an impetus to speed up+relaxation with the wife, then it is reasonable that it would lengthen the trip considerably, even within Westerland. Comparing a relaxed slow pace to one that was exceedingly fast to the point of repeatedly surprising multiple provincial representative, extrapolating that it took a good length of time just getting out of Marienburg should not have been that big of an issue.
Comparing the paces of movement is the key of the issue, between the two updates. One, when blitzing all the way down to Marienburg, and the other, slowly and contemplatively meandering back along the same path.
