While vacationing in Avalon. We played pickle ball and much to my disappointment open play with 30 to 45 different players was acceptable. Which my husband and I were quite uncomfortable with and decided not to play. Thank God Stone Harbor is doing it right and you must only play with your designated group of four for the 90 minutes court time. Plus the Pickle ball ambassadors match groups together that are less than four. Thank God someone had it right on seven mile island
