Just order your food and be assured it will go smooth. My worry was that Disney wouldn't work well with them but the opposite is true. The handshake between Disney and Garden Grocer was perfect!
Customer service was great. They called to go over the order within 24 hours after us placing it. And later called because they wanted to make sure that we had not made a mistake in what we ordered. (we were ordering food for 2 rooms but the information we provided was the primary room) They kept us updated on the status of the order and also advised us when it arrived at our Disney resort.
Everything was delivered on time!! Easy to use!
