@ScottsSweetie Thank you for your thoughts on your trip. I'll be on the Firenze at the end of August and I'm super excited for this different style of Carnival ship.
For the taxi situation in PV, if you walk down to the corner of the main street, by the gas station, there are taxi's there that will take you to the Malecon for about $6 for 2 people. I've done it many times. The taxis just in the port area are very expensive. Glad you made the most of your day there.
