If you are debating....use them! It was great. The food was delivered by bell services to our room within 5 minutes of our arrival. Having snacks in our bag at Disney was fantastic and made everything easier. Snacks in our room, especially fruit, made me feel good about what the kids were eating.
Groceries were delivered to the resort prior to arrival. Reputable company with great customer service.
Easiest, friendliest, greatest communication service I'be ever used!!!
