You are gretting great advice

We rent a car, but we always cab to our unit. If going to Orient from the airport I would reserve with Wilford Brooks - a TTOL sponsor, give him your airline info etc and he will meet you at the airport and will stop at a store on the way if needed. During hte wk we also use Wilfred in instances we don't want to drive

We get our rental car dropped the next day at our unit , reserved before you leave for SXM - we all have our fave [ours is AAA], but make sure you get an all in price in advance

If you want some supplies in your unit, book your drink / food order with Jeannie - Shop n Drop - a TTOL sponsor
Nothing better than cold beverages and snacks when you walk into you runit. Failing that there is Casino brand store in orient, plus some others for supplies

Last suggestions - we check in advance # of cruise ships in port and if any are super ships = they almost count as 2 cruise ships
If 5 or more ships in, we tend to stay local or get out and about early
I keep a list of times for the bridges and causeway in the car so we dont get got in a long line up

And if so inclined, Moon Splash on Anguilla early March can be fun, even if only the last day Sunday for lunch

Enjoy your stay
