Having breakfast in the room with small children is a major convenience!
We stayed at a Disney World Resort and being able to have groceries delivered was so helpful. We traveled with an infant so not having to worry about packing all his required essentials, we were able to have them delivered in a timely manner. It made our vacation experience even smoother.
Great service ,ideal for things you need but don't want to go looking for (ie) cereal milk, beers will always use garden grocer for this convenience
