Re: If they had 2 travel in time again, where'd you have wanted them 2
I have no idea how close the barrier gets to the main population of galactic stars, but TOS would seem to indicate that there is ample room for navigation since Voyager isn't going to be going for the full on out of the galaxy trip. They'd also want to be able to scan for resources, so I imagine keeping close enough to do so. I don't see how the galaxy would run off without them, just because they are traveling above the main body of stars.
A dull trip, folks looking forward to 20 or 30 years of aging thanks to the stasis units, assuming things go to plan. Not much to report to Star Fleet on, but no need to fight with every Tom, Dick, and Borg on the way back.
