We ordered our items about 5 days in advance of our visit to Disney (Old Key West). Everything was great and I was contacted several times (phone and text) to assure me that things were waiting for us at Bell Services. Bell Services placed refrigerated items in a fridge and delivered to our condo when we arrived too. All went great.
Service was great. Right after we checked into our room at Disney Art of Animation groceries were delivered. Definitely saved us money being able to not rely on the resort for all of our meals.
Garden Grocer was simple to use. It also allowed our family to have a quick and inexpensive breakfast and get out to the parks each day.
