We have been renting from the Dollar / Thrifty location at The Sapphire and have been very satisfied. Newer cars, good condition, excellent service (including airport pickup and drop off), and competitive rates. They have a web site showing available cars and rates, but we contact the manager there ( Leo Jubenot, ljubenot@hotmail.com ) directly whenever we're going to need a rental car on the island. Great guy to do business with, very honest and straighforward, and never any funny business.
