Just keep up the good service you have. :)
This service is great and a MUST if you're staying at a Disney resort/property. The money we saved on bottled water, alone, as opposed to buying in the parks, was worth it.
The service is wonderful! I ordered groceries 30 days in advance and then when I arrived at the resort the groceries were already in our room. The milk and pop was even in fridge. Everything was exactly as I ordered.
