Go to Costco.com and type in bottled water in the search engine. Then add it to your cart (you must register at this point, no cost is involved). Where it says address, put the address of the resort where you will be staying. If you want, you can put your home address as the default and the resort address as the ship to address, this is what we did. The cost has gone up to $7.69 but it is still a bargain. If you are leaving in 5 days, I would order the water today. It will be at the desk when you check in. We ordered late and had to wait but came back to our room from the park one day and the boxes were already there.
