Featherdance--What you state is definitely doable, yes. However, it appears that you have never been to SXM before. My advice to you is to rent a taxi tour for the day. It will probably cost you north of $100 for the day, but you won't get lost and potentially miss your ship, and you will be able to go directly where you want, and you won't have to worry about having a few adult drinks on the way. Renting a car takes a lot of extra time on both ends, and when you are not familiar with the territory at all and if you are late and miss the ship, it could cost you a LOT! of money..
