I think your best bet for the address is to call CBR to get the address. I had water delivered in May to POR and found 3 different address. I finally gave up trying to find the address myself.
Having said that..here is an address and phone number from a quick Google search.
I know for delivery thay have to have the actual physical address so this looks like it might be a good one

When I ordered on-line I put the name of the person who held the reservation followed by c/o Port Orleans Resort-Riverside
Bell Services left a message on our phone that our package was in and then delivered it very quickly when we called and said we were in our room.
I ordered a case of water on a Friday and it was at our resort Wednesday afternoon.
Ordering through Costco was one of the best tips on found on these boards..it was so nice to have the water and I highly recommend it to everyone.
