I would strongly recommend using Garden Grocer. It was the smartest decision we made. It was so great to have snacks and breakfast food in our room. Excellent service and follow through.
We've used GG for all four Disney vacations over past 6-8 years and every time found service to be dependable, product as advertised and site easy to use. When staying at a Disney resort you don't even need to be there to receive order. Bell Services will keep groceries (including refrigerated) and deliver to room when requested. No need to have car rental or take time to get groceries. Couldn't be more pleased.
Garden Grocer is great, order was at the resort prior to our arrival. They filled the order completely and met all of our special request. Will use them again on our next trip to Disney.
