Agree, not too may options available down here. Airport long term parking used to be $5 a day and $25 a week, but that sadly was quite some time back. Now is a straight $6 a day. But long term slots are only a 2-3 minute or so walk from the terminal, so you can arrive/depart quickly.

The other long term parking option I've heard of is at the airport area Radisson Hotel, about 4.25 miles from terminal. Heard some time back they charged $4 a day. Drop off/pick up pax using their shuttle. Not sure if this parking is still available, or if so of the current cost.

6 Mar '11 UPDATE: So many people are now parking long term in the short term lot, since short term is only $2 more per day than long term, that close in spots for those wanting short term are now difficult to find. Puzzles me, therefore, why folks don't just park in long term, if that's what they really need, and save the $2 a day. Honestly, it is only a 30 second longer walk out to long term!
