We plan to rent from Budget. Budget also has a free shuttle van to take you to/from the ship. Last time we did this the total cost of the rental was $30 to rent at MCO and drop off at the port. Not a bad price. Then we rerented from Budget to go from the ship to WDW and we stayed at WDW for 3 days but I don't remember the rental price for that half. It was simple and easy so we plan to do it again.
