We were there in October and used both Prime Now and food delivery apps (Uber Eats and DoorDash) without a problem.
Our groceries were delivered while we were flying down. I put a note in the special instructions section to deliver to bell services and tell them there were perishables that needed to be refrigerated. We picked them up ourselves after we arrived, but you can have bell services deliver them to your room for a $6 fee.
Food delivery services worked great too. One of our delivery people was even a Jambo cast member, funnily enough.
