I don't know what additional intelligence a scout could gather that Ploopploopeen hasn't already informed us of, unless we want to try and recruit P's son as additional muscle? Given the number of guard patrols, I think it would be very hard for Solace to escape detection. For these reasons, I think we should forget the scouting and just go now in a big group.
I would caveat that, though, with the observation that something is in the water, eating the offerings, so lets give that area a wide berth as we approach!!
