This was so easy... Our drinks and snacks were waiting for us when we arrived at our Disney resort! We'll be ordering again on future trips and have already recommended to others!
I would recommend Garden Grocer to anyone visiting Disney. The resorts are so huge that it is a significant trek just to walk to the restaurant each morning for juice, fruit and yogurt etc. It was a huge time and money savings just to be able to have a bite of breakfast in our room and then head out the the parks. In terms of value add, the best item we ordered was a case of water, it cost less than $10 for a case of 32 and I estimate that it saved us over $100 if we had purchased the water in the parks. The savings more than paid for our grocery order!
Order arrived at WDW resort before we got on the bus! Everything was stored properly, cold and delivered onto. Excellent way to shop when on vacation.
