This is the grocery we've used during our SSR stays. I'd say it's a 10 minute drive or less and the prices are much better than Gooding's:
Winn-Dixie Marketplace SHOPPES OF LAKE AVENUE
11957 SOUTH APOPKA VINELAND RD
ORLANDO, FL 32836
You can probably check my directions from their site but from memory: I believe it's a left turn out of SSR to Hotel Plaza Blvd, then another left at the plaza where Gooding's is - Winn Dixie is about a mile or so down the road. It's on the right set back a little bit - there's an ABC Liquor right in front of it. You can sign up for their discount card right at the cash register & I've found I usually save a few dollars by using it.
