Everything was good except the upsells
Cons: Of course car rental places will try to upsell you on extra insurance and the like, but this place straight up put it on my bill without me asking for it. They didn't even let me know it was going on my bill--I found out by looking at the invoice when I got home and connecting the dots. Overall, about $100-$120 I couldve saved on a weekly rental.
Regarding the auto-expreso pass, I bought it per reviews online saying it's useful, but I never had need for it. I kept track of what I would've paid in tolls each day, and it was never more than $2.50. The expreso tag is $5/day, and I think the island's 10.5% tax might apply making it even pricier.
