I was wondering if anyone has ever used smart car rental?

Yes we did rent from Smartcarrental and these guy's are great, they deliver the car at the Airport and have save us a ton in cash.
Try them you'll see the difference.
Go to their website http://www.smart-rent-a-car.com
I think they are also affiliated with http://www.arubadiscountcell.com
Have a wonderful stay in Aruba.

Thanks for the info i think we will use them.

what ever you do be careful of those jeep rentals!! my husband ordered one and they were kind enough to deliver it to the hotel. we discovered that the jeep did not possess a roof.... a very necessary item to have when exploring the desert! needless to say, we were torched! even with hats and sunscreen!! but we did laugh a lot! it was such a broken down piece of junk !! just like the horses we rented! i guess everything gets beat to death on that island!
