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.
Since it was our first time, I was a little concerned but it all worked perfectly.
I will use garden grocer again on my next trip to Disney. They are what true customer service is about, and that is hard to find these days. They let me know when the order was delivered and then called to make sure the order was correct. I highly recommend their services for anyone flying to Disney and don't have extra room in their luggage for snacks & beverages!
