When picking up the car, the male staff at Budget counter informed me that they no longer had the Ford Explorer I reserved. They only had a Chevrolet Suburban, a large SUV, available with an upgrade fee of $125 per day. Considering there were six of us with six pieces of luggage, we had no choice but to agree to the upgrade. Renting it for two days including tax came to $599.47, almost $270 more than the originally confirmed amount on Zuzuche.com! I thought the Ford Explorer I initially booked would have been sufficient for us and our luggage, but Budget's failure to keep the model we reserved resulted in significant extra costs. I will not be using Budget again. Compared to a friend's experience at another rental company where they got a free upgrade under similar circumstances and were even given an additional day's rental due to the larger vehicle's higher fuel consumption, Budget's service was disappointing. Additionally, the process to pick up the car at Budget was slow, and there were no staff to accompany me to the vehicle. They just handed me the keys, and I had to find the car in the lot myself. When I had questions there, no staff were present to assist. The entire pickup process took almost 45 minutes.
