We used garden grocer for our stay at a Disney resort in sept and the delivery was waiting for us when we got to our resort. The produce was fresh and they had a very good selection of items to choose from. We will definitely use them again!
We decided to order a few items so we wouldn't have to pack diapers, wipes, formula, food, etc. for our one year old. We were beyond impressed with this service. It exceeded our expectations. We highly recommend this service and we will use it again.
