We have used this twice when we have stayed at Disney and will use it again when we go.
The process was quick and easy and had no problem getting our groceries at Disney Animal Kingdom Resort.
This is a great service and I highly recommend it. We got the drinks and snacks that we wanted/needed without having to take a taxi. The delivery was made on time and everything was well packaged. This is definitely the way to go especially if you have a DP addict and are staying on DIsney Property!
