Since there was 6 of us with suitcases, we rented a Suburban and when we went to pick it up, there was none available. When I gave her my name, she kept looking at the sheet that was in front of her. I asked if there was a problem and she said, yes, we do not have a Suburban available. She excused herself and went to call someone. She came back to let us know that there was a mini van available. So, we had to rent that or would not be able to get to our final destination. We had to put suitcases under our feet and drive like that for a little over 5 hours due to the size difference of the mini van compared to the Suburban. The attendant was very nice and was as helpful as she could be with the lack of inventory. Very disappointed and would not rent from Avis again.
