Just a heads up. This is a much better place to have a rental car since there is lots of spacing for parking.
If you have a choice of stopping in Tiana for a few days its a better location for a car rental due to onsite parking
Using Eco Car seems to be a 1st choice of cruisers but be sure to be clear about car delivery to the marina with all the paperwork and CC machine versus having to be shuttled to their office at the airport and long lines which means waiting!!
