Other Car Rental Programs/Partners (ie. Alamo, Enterprise, Sixt) - any cautions renting convertible in Maui in august?

Traveling to Maui on my honeymoon in August. I have a convertible booked for 5 days. Wanted to find out from anybody who has rented the same if there are any warnings or horror stories I should be aware of and therefore look for an alternative agency.

Too many times I've booked a convertible online only to show up and be told that the location doesn't offer convertibles.

Thanks.

I was there in July and they were pushing the SUVs.... Their reason was that there was lots of rain along the road to Hana and the SUV would drive better... Since I already drive one at home, I opted for it just for the comfort level... I don't it makes a difference what car you drive to Hana. I've done it in a Cavalier before and this time with their Chevy Tracker.

Good luck and have a safe trip!
