The docks area sounds great to me if the others are in agreement with the plan to lure her to there and we can do our interrogation at a nearby empty warehouse.
I could walk into the Savant's Repose with the others right outside and see if she's hanging around the common area to bewitch on the sly and thus rely less on chance. With a change of cloaks, she would not notice the others walking 20 feet ahead of her as "following her" to the docks, as Crystalena can watch her without showing a "face".
