Borrowing a camera for SeaVenture

[longing4disney]

I understand that if you do SeaVenture at Discovery Cove, you can borrow an underwater camera from them for use during the adventure. After that, they put the pictures into a CD and you can buy it for $50. There are 5 of us, but DD is only 6 and can't do SeaVenture since the min age is 10. We decided that we will split into 2s to do this. Does anyone know if they'll let us borrow the camera on 2 occasion but then put all our pictures in one CD? Or will they make us buy 2 CD? If we need to buy 2 CD, I'm thinking that it may make better sense to buy a waterproof camera ourselves.
