I like the
Walmart on SR 535. The address is 3250 Vineland rd. Kissimee Florida 34746 phone:1-407-3971125
I like that they have the Walmart everyday low prices here which is not something that you can say about the supermarkets closest to WDW (The locals will tell you that these supermarket locations close to Disney Property jack up the prices)
In addition to groceries, this Walmart also has a liquor section, fresh produce and sundries in case you forgot something for the trip. I like to buy my pool noodles here now that Pastina, Paul, Ramen and Penny Noodle have left the country and are living abroad.
To go from the Beach club to this Walmart was around
$40-45 round trip with tip by cab and
about $ 20-22 round trip for the smallest Uber car. If you travel during the afternoon rush hour the trip might cost a little more depending on traffic.
