Arriving at MCO around 1am on 4/2 (flight leaves at 11pm on 4/1). Currently have an EE res starting on 4/2, ending on 4/9 for full size at $318.69. Looking to possibly arrive earlier (if DL has confirmed seats for same-day change - we are Plat Med) and depart a day or two later. Pricing on a new res shows $471.01 for 4/1-4/11 - that's over $150 for 2 more days. Would I be better off with the original res and then keeping the car an additional day or two or making the new res for the higher price and then just letting the chips fall where they may with the pick up/drop off times?

Hoping to get something at least as big as a std SUV though we've pulled Navigators and Yukons from the EE aisle before. I have a "backup" res from 4/1-4/11 at Alamo for a full-size SUV at $505.51 and a premium SUV at Budget for $538.31 so those are my worst-case scenarios.
