Cons: I was told that on return of the vehicle I could charge the rental fee to a different credit card. When I returned the vehicle, nobody was at the desk and there was a sign directing me to put the key, etc. in the drop box. I called when I got home and was told by someone in Budget's office (not the local office) that I could not change the card then and that I would have to call back in 48 hours to do so.
Pros: This was my first time using Kayak to get a rental car and it was a very easy process. The price was the same when compared to Enterprise Car rental but I had to enter discount codes to get the best price on Enterprise so this saved me the hassle of that extra step. Plus you can purchase 3rd party car rental insurance for less than half the cost from the renter.
