I have a question regarding refillable mugs. We are going in August for a total of 8 nights. The first 3 nights we'll be at WL because we were unable to book our entire stay at the Beach Club, but then we'll be moving to BC for the remaining 5 nights. So, do we have to buy one at WL and then another when we go to BC? Or will the mug we get at WL be valid through our entire stay including when we move to BC?
