Lori -- I wanted to speak up here before I forgot! I have to preface this by saying that I have never once had a Vons delivery at a Disney-specific hotel, or a good Neighbor hotel -- so I can't specifically speak to that part of the Vons delivery experience, which is mainly what you need to know and have gotten great answers about in this thread already. But I have been ordering from Vons at home since 2004 or before (I think they changed their computer system after the first times I ordered from them, and then began sending me email confirmations in 2004). I have had well over 130 deliveries from them. I would have had even more deliveries from them, except for the fact that for a couple of years I was also using Albertsons' delivery service (which no longer exists in my area).
I have to say, the Vons delivery service has vastly improved over the years. It used to be very iffy, with constant mistakes and problems with my orders. It has gotten so much better.
The great thing about a Vons delivery is that you have full access to everything in the store. If you have a Vons Club card or account (even just by using your phone number), you can get all of the weekly sale prices on the delivered items. if you have a Vons Just for U account, you can get those savings on top of the regular Vons Club savings. Not only that, but there are also savings and promo codes exclusive to online orders, so you can get the promo code savings on top of the Just for U savings, on top of the Vons Club savings -- depending on what you order, of course, and if it meets the requirements.
Not only can you order alcohol, but you can order flowers (let's say you wanted to set up a nice arrangement in your room), fresh fruit, meat, juices, foods from the deli, soaps and all other hygiene products, aspirin, etc. Anything that you could possibly get in a regular store, you can have delivered. If you're celebrating a special occasion and want to eat cake, you can order a whole cake -- or maybe just some generously-sized slices of cake -- to be delivered with your groceries. You can order a package of cupcakes from their bakery. If you want to eat pie and ice cream, you can order a pint of ice cream and a pie. If you want to order a 24-pack of bottled water, they have that too.
It's really so convenient. I have not needed to order from Vons when I've been at DLR because my stays were never quite long enough, but I swore that if I ever stayed a couple of nights longer I would order a Vons delivery to the hotel.
