  Hey Michele. I think you should do whatever works best for you, but I decided not to do it in the round, even though I saw the pattern adaptation (thanks to the person who did that, though I confess I forgot your name).
I tend to do anything I can in the round, but I decided that it would be more trouble to keep track of the increases and decreases around the waist than it would be to sew the darned thing up when I was done. It's only four seams and two of them are just an inch and a half and can be kitchenered if you want.
So that's my $0.02. But I fully support you if you decide to do it in the round, and I'll be interested to hear how it goes! As for me, I have done maybe two rows today, sigh. It took DD TWO HOURS to fall asleep tonight (2-year molars will be the death of me!). So no downtime for me! Well, I suppose I'm just staying up late for it instead. :) Cate
