Five trips to Aruba in five years......my recommendation????
Hans at Tropic. GREAT (read: best) price; great vehicle; fantastic service. The price he quoted us was almost $300 less for 2.5 weeks than any other car rental we checked with.
Hans or a representative will meet you at the airport (both when arriving and departing), walk you to your vehicle, do all the paperwork and take a credit card imprint and off you go. Didn't even take 10 minutes last year before we were out of the airport. Departure process is even easier. He helped unload our luggage, took the keys, checked the gas gauge and that was it.
The others we have used have their offices in a small row of buildings across from the entrance to the airport. We have waited as much as half an hour before being able to get in "our" car and leave. NOT much fun when all you want is to get a drink in hand and hit the beach.
Give Tropic (Hans is owner) a try.
