I ask because I have a decent rate on an Full Sized SUV for $321 (inclusive of fuel service option) for 6 days in June from MCO. Using some recently posted codes, I can get a minivan for $258 (not fuel inclusive) but the code requires a Saturday night rental. Has anyone ever booked a full week and then dropped their car off early? Are there penalties associated with that? Should I just keep our SUV? I supposed that tank of gas is equivalent if not more than the price difference. Thoughts?
