I would absolutely recommend the garden grocer. We purchased water, fruit, and breakfast items for the week, as well as snack bars to carry in the park. We saved money by not purchasing expensive snacks at the parks and didn't have to hurry to breakfast every morning. When we arrived at our hotel, the groceries were delivered to the room! Much better than having 20 minutes to run through an unfamiliar store!
This is an awesome, convenient service. The prices are no higher than premium grocers in ny area. Food was delivered before I arrived, and we were notified of the arrival via email. Disney stored it perfectly until we arrived.
You made it so easy to travel and have affordable food available!
