This is referring to travel that takes more than 2 turns to complete, primarily sea routes on Dwilight. The last few hours/miles and the first/few hours/miles of each journey would occur using the current system.
I find it strange that one has full access to guild/temple treasuries while traveling. Wouldn't it be more realistic to remove these options?
I would like to see something like a tournament-return page, where options are fairly limited.
And on the other side of things, I would like for sea travel to be faster. At the very least, I would like the option to purchase passage on a faster ship. Also, it seems less realistic to me for sea travel to be slower for larger units. A unit of 10 men should travel at the same speed as one containing 50, and a trader with 2 caravans should travel close to the same speed as a trader with 12 caravans.
