The Portugese action space says the following:
Give up one die showing a “6.” In return, you advance exactly 6 unoccupied spaces on the river and get the applicable earnings.
So, let's say you are 4 spaces from the end. Can you use the Portugese space to move to the end?
I would say no since it says "you advance exactly 6 unoccupied spaces."
But I can't seem to find anything more in the rules about it. Any ideas?
