THESE PEOPLE ARE SCAM ARTISTS. I booked a reservation for a car online prior to my trip. Thinking everything was paid in full and my car selected, I went to the counter to pick up my car. The woman asked how many people I was with: "One" and where I was going "to my friends house for the weekend". "I have the perfect car for you," she says. I signed an electronic screen a few times, got the keys and was on my way.
It wasn't until after I returned from my trip that I saw an extra $30 fee on my credit card (more than half of the full rental for the weekend). After calling customer service they told me that I received an upgrade and signed a rental agreement and there's nothing they can do about it but refund me half.
Do not give them your money! Do not trust them! This is the first time I've experienced this so I'm not sure if it is Budget Rental Cars as a whole or the Cleveland Airport location in particular but unless you want to throw your money away on something you don't even know you're getting, I'd suggest going with ANY OTHER CAR RENTAL SERVICE.
