Additional charges were not disclosed when signing the contract, and no electronic contract was provided.

The attitude of Budget in Seattle was quite good. They might have realized we were returning customers through our conversation, so they didn't dare push additional charges.

At the BUDGET counter at Seattle International Airport, I booked a Ford Expedition, but they didn't have the car. A female staff member at the counter asked us to wait, saying she needed to consult the manager for a replacement. We waited for 45 minutes. When we finally got to the parking lot, the car she gave us couldn't fit our luggage. I specifically booked the largest car, and she seemed unsure if the car would fit both us and our luggage. She didn't even offer a discount for giving us a smaller car. Luckily, the parking lot staff were kind and helped us pick a Toyota Sienna. Although the Sienna's performance doesn't match the Ford, it was a hassle to finally get a car at noon after arriving at 9 AM.

There are additional fees.

I rented a Ford Escape. The counter staff suggested that they would try to see if they could upgrade our car for free. They helped us upgrade to a Toyota 4Runner which was great. The staff claimed it would be free. But I was charged the upgrade free in the end which I overlooked in the small print and signed for.
