When you have major hotel chains recommending you then you don't need to do much else !
I have never used an online grocery service. The website was so easy and it was nice not only getting a confirmation email after the order was placed, but a phone call confirming the day/time of my delivery.
Saved us time on our trip to Disney World. It was so nice to arrive and have our groceries waiting for us. We will definitely use the service again, thanks!
