Stellaris and the Surf Club (Marriott Vacation Club) are located next to each other. Is there a reason that you are not booking a car for the 10 days you are there? The parking is free at the Marriott property and if you take island tours and go out to restaurants the price of taxis and shuttle services will be much more than renting the car. The car also gives you the freedom of making your schedule as opposed to following a schedule set by others if you do tours/excursions. Aruba is a very easy island to drive on and the parking around the island should not be a problem...especially this time of year.
