Superwalmart near Thousand Oaks

[WDW Dreamer1]

We are staying off site at Thousand Oaks in Davenport Exit 58 off I4. When we arrive we will be going to Universal Studios for the day but would like to stop on the way home at Superwalmart. Any advice on which superwalmart is easiest to get to?( on and off the highway the quickest?) According to the map there is one on Turkey Lake and one past exit 58 in Haines City.
