We've been using Garden Grocery for as long as I can remember. Our oldest has food allergies, and when we travel to Disney, we are careful to bring along food that he can eat. GG went out of their way to add items for allergy folks over the years, but when we first started using them, these items were special requests. And it was super easy to make special requests. High customer service. They care and they check back to make sure everything goes well. We use them every trip and recommend them.
Buying water and breakfast items saved us a ton of money and time at the parks.
