We used Garden Grocer for all of our breakfast meals at Disney World, and saved hundreds of dollars over what we would have paid for a meal plan. And we had extra snacks every day! Would do this again in a heartbeat.
This was a great service it was so nice to arrive at our hotel and have the grocery delivered that day. It meant we had drinks and snacks to take to the park each day. It's worth ordering early to get the discounts as well.
We've used Garden Grocer every time we've gone to Disney World. Everything we've ordered is always very well packed, separated into refrigerated items and dry goods, and waiting when we arrive.
