I did the 1-10 water quest just to see how it would turn out. A couple things Ill add.
Restock water flasks from the lady near North Qeynos gate, not #22 on map. There are 2 corrupt guards that block your way during the day.
Make sure to hail lock Lasen by hailing between every turn in.
2-3 hours seems a bit too optimistic. This took me 4.5 hours, but also I guess I had never done this before so I had a bit of a learning curve. I lost Lasen a couple times when restocking.
Buy instruments and songs beforehand and put points in instrument skills as you level up so you can skill up during the night.
I now have a great EC mule
