Yes, Dunns river does have lockers, I am sure we paid no more than $4.00 for locker. We used it to put our ID's and towels but I would not bring anything expensive because when I was there this lady from the Couple's hotel we stayed at brought her CamCorder and asked one of the locals to record them at least until they got to the first level. When she got to the first level where he was suppose to be standing filming the lady and hubby, the guy was gone. One local took my hubby's Tommy Hilfilger hat right off his head and ran so please be careful and don't wear any fancy jewerly or anything you don't want ripped off. As for the Stingray tour. (we took the one in Grand Cayman and we put our ID's and towels etc in a tote/beach bag and left it on the catamaran and it was not touched. You will really enjoy stingray tour.
