OP, if you're checking in (or out) and need the lockers, you can check at the gym to use the facilities there. I know that is how they work it at WLV, BWV, and BCV. The only resort I know of that has the lockers and dressing areas is OKW. I've never stayed at SSR, so don't know about them. I would imagine Kidani is the same, since their gym is near their pool.
