Just going to post my two cents worth
My March 2019 trip
Stayed at Disney's Old Key West Resort
I used Uber
Walmart Supercenter (has a full size liquor store attached)
$8.29 USD OR $11.41 CAD going to Walmart Supercenter
$11.26 USD OR $15.50 CAD return to resort
Total cost for return trip was $26.91 CAD
Saved a ton on a case of water, fresh fruit ,snacks, and a few souvenirs also.
Picked up a few snacks we do not get here in Canada.
Address is on Vineland.
