We originally had an AVIS rental from MCO to Raddision AVIS rental center (we are flying in the day before in case of any weather delays with our flight and staying at Raddision for the night )and then after the cruise, an AVIS rental for our 8 days at Disney then drop off at MCO.
We always look for better rental prices any trip we take as the weeks get closer. We now have a 12 day rental with National for a Full Size car instead of a 9 day Intermediate size car for $30 less than the AVIS reservations. Since we chose the 1 Bedroom Cruise Ship Package at the Raddision we also get free parking for the duration of the cruise and shuttle service to/from the Disney port.
Bigger car, more time, $30 less and no daily parking fee's. And I will still keep looking till the last day for any better deals.
