We only paid $29 for a 1-day car hire in March so it is definately cheaper than a taxi and you get a tank of petrol as long as you take the Gold option, otherwise you can pay a huge amount for the gas when you return it. We were able to return it to the place on the 192.
We plan to do the same later this year when we are arriving at Tampa. Reminds me I must get it booked!!
