We were there in August 2024 and had groceries delivered from WalMart. I used a TD Visa. No issues at all. My order was correct and driver was right on time. They delivered to Drury Hotel at Disney Springs. We are from Ontario and had no problems.
I had to sign up on the US Walmart but I did it before I left and made and paid for my order from home. We had a car so we did the pick up service where they bring it to your car.
I have never made a grocery order anywhere until I went to Disney. I just ordered online (about 4-5 days in advance) from the Walmart closest to our hotel and picked a date/time that I knew we would be at the hotel. I just placed my order and plugged in my VISA. No problems.
