Oookay. Rafting across the Aldani Basin it is. The rafts only go about 1 to 2 miles per hour, but you don't get any further on foot than that and it's much harder work on foot (hacking through jungle). Also, in the Aldani Basin, it would be very wet on foot.
BUT, most of the time, it's not terribly hard work to sit aboard the raft, even if you take a turn poling, so it's not difficult to make a long day of it. If you want to set a fast pace, and try to get 20 (or possibly more with a check!) miles in a day, it's totally doable.
What do you think?
