You can buy a thermal cup for $10 for which you can have free refills all day.If you come back another day you can just buy a new barcode sticker for half price.
$6 chris and it helps if you take the cup back with you !!![8D][8D][8D]
also you can get ice cold water from the refill near the shark swim and all taps will work at once when you flash the barcode. great if you holiday with gremlins. do you remember that bit in the film when the gremlin lays under the beer tap and blows up its belly?? one of my favs. [8D]
