I've never had water delivered but always go to the Hess station at DTD to get a case of water when I arrive. Just take the bus to DTD West Side(the second stop) and walk across the street. They sell cases of 24 bottles of water for under $10. Once I get my water, I walk back to the DTD bus stop and take the bus to my resort. I always do this alone, but if you have more than one person you shouldn't have a problem. You can always have them put the water in bags or bring your own. I've done both. Just a thought in case you want other options.
