As far as I’m aware, Garden Grocer is the only delivery service who will deliver alcohol to the resorts without you being present. You have to submit ID online beforehand.
AKV Kidani said the same thing to us last year. Said they always have everything organized, their own carts to transfer things, and are just very easy to work with.
We used Walmart+ in Sept this year. Part of the delivery came separately, which was weird, but they did show up at the beginning of the scheduled window. It also seems common to get delivery there, so they provided detailed instructions for pick-up, which was helpful as a first time WDW visitor. I especially liked that you could schedule an order and modify (add/delete) items up until a few hours before the delivery, just in case you think of something else you wanted to add.
(Walmart+ has a 30 day free trial, which is what we used.)
