I do not think any type of improvements need to be made. Was super easy and it appears you have perfected your service :)
Great service! Everything was delivered and waiting for us in our room. All the perishables where packed separately and in the fridge.
we stayed in a villa which included our own kitchen, had read that Garden Grocer offers grocery delivery. Very simple, easy, efficient to use. I would definitely use their service again if in Disneyworld or in the Orlando area.
