Budget - Pick up and drop off at different location is extremely expensive

Hello, I will be going to Orlando, FL between 9th and 20th.

9th-14th, I need a car (preferrably SUV or at least medium size)
14th-19th I dont need a car and i am staying in Marriot at sea world.

For my rental 9-14th (return at close to Marriott) costing me around $641. If i rent for the entire trip and return the car at MCO, it will be $275 with wendies offer. But Marriott is charging $16 for parking.

Also tried with hertz(Marriott has rental location), it is coming around $290 for 9-14th.

If i am returning the car on 14th, then i need to take cab to the airport from hotel on 19th.

Do you guys suggest any other options for me?

Return the car at MCO on the 14th; then, take a taxi, an airport shuttle, or a separate one-way, one-day car rental from MCO to the Marriott (or to a car-rental location near the Marriott).

The Wendie offer is good for a rental from April 9 to April 14. Of course, you might get an even better rate if you put in a bid on, umm, Priceline.
