Here's another thought. If you mean Sarasota, FL then you are basically driving right past WDW to get to MCO, so actually going almost 2 hours our of your way to return the car at MCO. Have they looked into returning the car closer to WDW property. Most of the major car rental companies have return areas near WDW, some even provide transportation locally. They can still take ME back to MCO if they do that.
