Yep. Although in this case it's the airport imposing the extra fee on the rental company which they are passing on to you. Since it will cost you more than $25 in a taxi to get from City to the airport, there's no easy way to save on this. There's no convenient bus, either, unless you use a hotel shuttle, which charges about $16..

I tend to use independent rental companies like [IMG]Ace[/IMG] who you can negotiate some good deals with.
