Forget the gas station and the taxi to buy groceries. This is the only way to get your groceries if you don't have your own car. The food is delivered on time and the prices are better than your local resort shops. Empty out a suitcase to carry your groceries from the resort delivery room to your room. The food planning is the hardest part.
Garden Grocer was great. I used their app to make selections for our upcoming Disney trip. There was one thing that was forgotten in our original order, but when we returned to our room the next day, it was waiting for us in our freezer!
Great, prompt service!
