We've used Garden Grocer several times now. We order mostly breakfast items for our vacations but we used to order things like diapers and baby stuff so we didn't have to pack it! GG has always delivered on time - even early - and we have always been very happy to have our food waiting for us when we arrived!
I found Garden Grocer when I was looking for a grocery in walking distance to our hotel. It was the answer to our dilemma - staying on (Universal) property without a car. Ordering on line was easy. We got a phone call the next day to confirm, and the food was delivered as requested, in our room when we returned from a day in the park. I would reccommend this to anyone who doesn't want to spend $4 for a bottle of water or $12 for breakfast.
Stayed at a Disney resort and ordered from Garden Grocer. Everything was delivered as ordered and on time. Also had follow up calls and email to verify order was correct.
