The time to move them around won't hurt them at all, just lift them slowly when you pick them up for the first time if they appear to be stuck to each other, the tub, etc. You do NOT want to tear a hole in one. I was out of town for a clutch once - I think the eggs were laid 36-48 hours before I found them, based on dimpling. They all hatched with zero issues, just looked a little more deflated than my clutches usually are. I can almost guarantee you your girl won't lay on schedule, which could mean WEEKS off work if you were going ot sit around and wait for her. Now if you just need a good excuse for a vacation, then go for it!
