We have used this service for 2 trips to Disney world. Both times the orders were correct, packed well, the fruit/veg were decent and it was waiting for us at our hotel when we arrived. Definitely use them again for our next trip.
We had a very short period of time to spend enjoying our family vacation. Not having to worry about finding a grocery store, spending the time shopping and lugging it all back allowed more time to lounge around the pool.
