Pros: I liked the convenience of booking in advance at what seemed like an excellent fare. Too bad it was all wrong.
Cons: The insurance that I was sold online did not meet the local requirements. When I arrived I was told that my 4 day rental would go from <$50 to $180. The required insurance was over $110 and and was not mentioned until arrival at the counter. I was also charged $5 for gas eventhough I returned it with more fuel than it had when I picked it up. Charged for an additional driver and was told that it was standard regardless of how many people would be driving. Generally felt scammed.
Pros: The price was amazing at first, $4 per day and $9 for insurance.
Cons: The $9 insurance purchased through kayak was not recognized in Panama by budget and I was forced to buy insurance through Budget as well. The cheapest insurance was $18. It was still a good deal but I felt a little deceived by the price because the obligatory additional insurance was not mentioned as far as I know and the insurance I did by wasn't recognized by budget, so basically a waste of money turning a good deal into an average deal :(
