Good overall, but have had better
Pros: The people who work for Alamo in my experience have shown excellent customer service. On both sides of my drive from SF to NY, they were knowledgeable, helpful and friendly. The vehicle was in good shape and I experienced no problems driving across the country.
Cons: No rental providers have full-size van options available. So I don't hold that against Alamo individually. However, the Chrysler Town&Country I rented had the auxiliary audio and Bluetooth disabled, which for a week-long cross country trip was extremely disappointing. In the past 3 years, every rental I've purchased had these features standard.
