IIRC, that's a very long trip, and there is a bug regarding long distance travel with advy/priest characters. Essentially, as soon as you leave, it keeps telling you "one hour left" until you actually arrive. Which could take anywhere from a few hours to a day or more, depending on the total distance. For example, if it was supposed to take 40 hours, and you had 16 in your pool, then you will not arrive for 24 more hours. And even then, you will have to wait for the next turn change to actually arrive. So, give it a while longer. And if it is still stuck after another day, report it on the bugtracker.
