I'd definitely go with the EF 15/2.8 fisheye if you can find it, it is much cheaper and lighter than the EF 14/2.8L II (I have both), similar IQ, and better suited for the milky way, IMO. Great for northern lights, too. The f/2.8 instead of f/4.0 is important. Of course, it is a fisheye so special purpose, but the EF 14/2.8 is also extremely wide and about as special I would say. Most important is to find as dark skies as possible however, and from your travel plan it seems you can get away from artificial lights, which is great. But you said you're going in the middle of the summer, meaning the night will be short, so you'll have to make sure to get the stars during the darkest hour.
