Cons: The agent was great - there just wasn't a car available.
And the insurance I had paid for online was not showing up in Belize and could not be transferred to the local rental the Avis rep put me in touch with.
Pros: The rental process was just as ez in Belize as the US. The Suzuki Jimmy performed excellent and was efficient on gas which was $5 gallon. All the rental clerks were friendly and got us on the road quickly.
Cons: This is a tiny SUV , ok for 1 or 2 people but cramped for any more if you have luggage.also the maps are not great so have an alternate.
