I asked for an upgrade and was very happy with it.

Platform was simple to use and also saved me money by rebooking the car for a cheaper price!

Your car will allocated to you - you will get to choose a vehicle.

Everything worked fine

The rental desk and parking lot are directly connected to the terminal, and it's very close. Unlike other cities, there's no need to take a shuttle bus. The pick-up and return process is very convenient.

Very friendly staff, was offered an upgrade for $10 a day but was charged $30 a day. I wrote and complained to AVIS and they refunded me the difference immediately

Like: Rented a mini van and then upgraded to a full size Ford Expedition - all was perfect
Dislike: I was in the middle of Hurricane Irma, and I could not add additional insurance to cover the car over the phone and all the locations around me were closed. I called the Avis for help and then told me to go to 2 locations which were were closed.
