Nope. We don't stick around the hotel much, so they end up being a waste for us. If we get something to drink in the morning, then we either have to bring the cups back to the room, or bring them with us to the parks. We use our DDP for lunch and dinner at the parks, so we don't need the mugs for those meals either. We are able to drive to WDW, so we bring an ice chest full of water, milk, juice, diet soda instead.
