Depending on how often you plan to eat at the food court and spend around the pool, they're a great savings. This topic has been written to death and the newer mugs have a tag on them that says "Good for use during this stay only" or something like that but we bought mugs about six years ago and I take them with me every time we stay at DxL. I've had cashiers say, as I'm paying for my food, "you know that mug is good for as long as you own it". We stay onsite a couple times per year and I'm sure that what we paid for the mug has probably just about covered the actual cost of the coffee and soda we've consumed.....not retail but wholesale.
