I have it blocked where this week (8-14) will have Balamb as the "focus". So the bulk of events and NPC play will be right here on our home turf. Next week (15-21) will be in Galbadia and the week after that (22-28 although it might run long just because it's a fun, wintry place and this is December) is Trabia. So Sabin could go now and be gone from Balamb for a total of three weeks, or wait until the highlighted activities period and only visit each respective Garden for a single week each. I hope this makes sense and my fried brain isn't being too confusing :x
