They don't tell you that most of the trip on the intra coastal, you can only go 2 mph.
Even though I booked the trip with my Amex card, they informed me that I couldn't put the security deposit on my Amex and needed a different credit card. When I informed them I didn't have one, they suggested using an ATM and withdraw $300. When I said no, they found a way to accept my Amex. Then when they charged me the $300 deposit, a tip window came up with 15%, 20% or custom tip based on the deposit, not the cost of the rental.
