What beaches can be accessed by water taxi??

We will be in St. Maartens in October and wondering what beaches we can get to using the water taxi? (We have a 1yr old and 6yr old and no car seat, so its walking or water taxi) We were going to do Great Bay but I'm reading about the pollution there and a little worried with 2 small kids.

The water taxi from the cruise terminal only goes to Great Bay. I suppose you could hire a boat to get to some other beach, but that could be very pricey.

You could rent a car - with a baby seat, and then hit any beach.

Or make prior arrangements with a taxi service (such as Wilfred Brooks Taxi Service - google him if you are interested) to take you around and have a car seat. Not sure what it would cost. Brooks is totally reliable - if he is unavailable he may be able to recommend someone else reliable.
