I used garden grocer when I went to Disney World, and my order got there before I did. The online process was easy, and they delivered as promised.
Garden Grocer has a good cross section of items available, is easy to use and the service is impeccable. It really helped with the food budget to have snack and breakfast items in the room and made packing much easier because things like shampoo, sunscreen and laundry items were delivered to our hotel room instead of having to be packed. I wouldn't travel to Universal or Disney and NOT use their serivce--it was GREAT!!
Excellent customer service. I made an error with my arrival date and the issue was resolved immediately with no problems although it was my error.
