Has anyone used Advantage car rental? We are flying into West Palm on Aug 15, and flying out of Fort Lauderdale Aug 20. Need a minivan, as we will be moving son into college dorm in Miami. Prices are exorbitant at all the major rental companies (over $600), yet Advantage is only $251 for the week. I have never heard of Advantage, am a bit nervous, although I did book thru AAA. Any experiences with this company?
