Port Canaveral - Avis vs. Budget?

[Dani24]

We will be renting a car from MCO to Port Canaveral for two days ahead of our cruise. I'm looking at booking a car through either Avis or Budget because I can get a car from either of those for less than half the price elsewhere, through my work. 

It looks like they're a little bit farther from the port than some of the others, so I'm especially interested in the comparison of their shuttle service. We're sailing on Princess, in case that matters.

We tend to rent from Avis, and have always had good experiences with them, but I know locations can vary. And I'm interested to hear direct experiences from others.

We've rented from Budget. It worked out very easy for our extended family of 6. DH dropped us and all our luggage at the port. Returned the car to Budget and caught their shuttle back to the port. Quick and easy.
