To avoid the crowds, book your tour early. Not too early as this is a tender port and some ships have a problem getting passengers off the ship in a timely manner here. But the earlier you get to Stingray City, the better. Also, thats where taking a tour independent of the ship is better, you wont have that boat full of 40-100 people. Private tours will take you to a less crowded area of the sand bar.
